Onix Z5 Graphite vs Fiberglass Pickleball Paddles Review: Which is Right for You? (2023)

Ever wonder why you see the Onix Z5 floating around the pickleball courts ALL THE TIME?

Our Onix Z5 Pickleball Paddle Review will explain why both the graphite and fiberglass, Nomex core paddles are still popular today.

There are some really good paddles on the market but the Onix Z5 stands the test of time and continues to attract players of all levels.

There are very few matches where you’ll not see at least one or two players wielding an Onix Z5, whether it’s the graphite version or the fiberglass option.

With the Onix Z5, you’ll get a good mix of a high level of technology, well-tested, traditional widebody design, and an affordable price.

Both the graphite and fiberglass versions of this paddle enjoy a large sweet spot and lots of power.

The major difference between the two is that the graphite model has a lighter head while the traditional fiberglass model is heavier and more of a workhorse. Both have a widebody paddle shape.

Both provide a good feel when you’re playing around the non-volley zone.

The Onix Graphite Z5 feels more controllable due to its lighter construction and the face provides plenty of spin when required.

The graphite face does appear to offer more feel and is more forgiving when playing cross-court dinks. The paddle’s ability to control the ball is appreciated by all who play with them, giving even new players confidence to attempt shots that they may otherwise not feel are on.

This resin-dipped, cardboard-like core is more “old-school”, but it’s durable and provides lots of punch for groundstrokes and overhead volleys. It’s less likely to soften and give your paddle dead spots.

The fiberglass face isn’t quite as rough as the graphite one, which gives the graphite Z5 the edge in providing spin.

However, the fiberglass face is no slouch in this area, and beginner to intermediate players will be hard-pressed to discern any major difference in the spin characteristics between the paddles. 

Both paddles are USAPA approved for tournament play.

Paddle At A Glance

This is a widebody paddle, making it perfect for beginners to hit accurately and with power. At over 8 ounces, it’s not quite as heavy as the composite paddle, but it is still a solid paddle that can be a bit heavy for smaller players. But, with its wide sweet spot, and wide face, miss-hits are reduced.

You’ll be able to generate plenty of power from the traditional Nomex core, with the graphite face providing a stiff surface that is responsive and long-lasting.

Paddle Surface & Core

The graphite face is solid with plenty of roughness. This makes it ideal for those who like to put lots of spin on their shots. The Nomex core provides plenty of rigidity, giving the paddle plenty of “pop”.

The core is set up to provide plenty of power. Nomex is a cardboard-like material that is dipped in resin to give it rigidity. With the large hitting area and huge sweet spot, it’s hard not to hit well with this paddle. This is why it has such wide appeal amongst new and intermediate players. It provides plenty of accuracy, allowing players to not only place their shot but to do so with a lot of punch.

The core is exceedingly durable, so it will put up with plenty of abuse and not develop flat spots which plague some other paddles.

The combination of a firm core and graphite face provides the paddle with a great feel. Players report that both hard and softer shots are easily dealt with. 

The ability to vary the pace on the ball and impart spin when needed give players plenty of options.

The honeycomb core is able to provide a very durable and strong base on which to layer the graphite face. The two materials complement each other by reducing the weight for ease of handling and feel while still offering players enough pop to be dangerous.

Graphite is lighter than fiberglass while still providing a rigid, high-performance paddle. 

Fit & Look

The grip is not particularly long, but it is quite skinny. Even players with small hands may need to adjust the grip by adding a bit of tape to beef it up.

The wide face gives plenty of contact area, allowing you to reach most returns with ease. Its traditional shape makes this a paddle that is easy to play with, which accounts for its broad appeal.

It comes in a variety of colors and designs, so there’s something for everyone’s taste. You can order a paddle in a traditional black with blue graphic or one of the other more exotic designs in purple, yellow, orange, pink, green, white, or yellow.

Paddle At A Glance

The traditional wide-body shape and large sweet spot are the determining features of this old-school paddle. It’s not hard to miss the large Z-graphic on the face, with even some professional players opting to wield these paddles in tournaments.

The paddle is a couple of ounces heavier than the graphite model and this is put to good use when players need extra power in overhead smashes or when playing off the baseline. When you need that little bit of extra bite to help with control and finesse around the non-volley zone, this is the paddle that you want in your hand.

Paddle Surface & Core

The fiberglass face and Nomex core are a little heavier than the graphite model and you can feel it. The paddle feels more substantial with bigger players enjoying the extra power they get from the weight advantage.

The time-tested core provides a rigid paddle with the fiberglass providing a large sweet spot. It is both durable and responsive while providing plenty of feedback. The composite finish provides enough roughness to give your shots the spin you require. 

Some players prefer the extra roughness that graphite gives the face, but the fiberglass paddle’s spin characteristics are top-notch and there’s little to tell the two apart when it comes to applying spin.

Players love the power and accuracy they get from the paddle. The Z5 is known for its solid feel and this comes through loud and clear when you hear the ball hitting the surface. It’s not the quietest paddle, but it is not billed as such.

The paddle doesn’t provide quite as much spin as the graphite finish, but it’s still controllable. 

While there are now many elongated and other unusual shapes on the market, the traditional, wide face of the Onix Z5 provides a simple and elegant paddle that offers a large sweet spot and excellent control characteristics.

The paddle is not so long that it becomes unwieldy when reacting to shots around the kitchen. Players appreciate the balanced feel and ability to adjust their position no matter how quickly they need to respond.

Fit & Look

This is a distinctive paddle that has been around for many years. There are plenty of design options and more than 10 different colors to choose from, so finding the right one is a certainty.

While the handle is not overly long, it is adequate if a little too thin for most players. This is easily fixed with the application of some tape though. 

The paddle design is traditional without the use of elongated and exotic shapes. This seems to work well with beginners and intermediate players sticking with the tried and tested design.
