Genesis New is a new co-poly that gives players good control without losing the feel of the ball. New is a crisp but comfortable poly that promises to give players predictable control and enough pop to finish points.
I tried out New Cyan 125 in the Head Speed MP, which is a racquet that already has a fast acceleration and a large sweet spot. My first impressions were good: the energy transfer was clean, the launch angle was reliable, and the strings felt connected. Some spin polys can feel too wiry or loose, but Cyan has a nice “grab” on the ball but stays stable through contact.

Head Speed MP Playtest
Genesis New feels clean and plush right off the stringer. It doesn’t need much break-in time; the response is direct and easy to predict from the first swing. It gives better feedback on the ball than stiffer polys without feeling too soft or mushy.
The launch angle on the Speed MP is quite high anyway but this tames it a bit which is a big plus. I could swing big through the court without worrying that the ball would suddenly sail away. The combination of spin access and directional stability made it easy to hit aggressive cross-court drives and flatten out balls when I needed to.
Control stayed the same for the first few sessions. It felt more solid and connected than a lot of other round co-polys in this group. The string’s smooth surface still lets it snap back quickly, giving you a good mix of spin and drive, even though the maximum spin isn’t as high as ultra-shaped strings.
The string started to get firmer and the power dropped a little after about 6 to 8 hours. However, it was still playable and never got too harsh or unpredictable.
Overall On-Court Impressions
Here’s what stood out the most in the Speed MP:
Pros
- Clean, predictable control on flatter shots
- Very solid feel yet felt responsive
- Moderate launch angle gave me confidence to attack
- Average tension maintenance for the category
Cons
- Spin isn’t as extreme as shaped polys
- Can feel firmer late in lifespan
- Not ideal for players needing extra lift/shape
- Less explosive pop vs. top-tier power polys (e.g. Alu Power)
I think Genesis New works well with modern power racquets like the Speed MP. The stable and predictable launch angle helps keep the ball in the court when you swing big.
Break-in period
Genesis New feels responsive after about 30 minutes, unlike many firmer polyesters that need time to soften and settle. The stringbed feels tight yet connected right away, with very little need for adjustment.
The tension does go down a little bit in the first 2-3 hours, but in a good way. The ball pocketing gets a little better, but the launch angle and directional control stay the same. There isn’t a big change in how it feels, and most importantly, it doesn’t go through a “tinny” phase like some round co-polys do at first.
If you don’t like strings that feel too stiff or erratic for the first few hours, Genesis New is a great choice.
Comparable Strings
Closest matches for me are:
- Head Lynx Tour — Although shaped the control and feel do feel similar
- Nordicdots CS125 — similar feel, but I think New gives cleaner response
- Solinco Hyper-G Round – Slightly firmer than New but does remind me of the clean contact and consistent launch angle
Interestingly I think New is marketed for power and feel but I actually found the power quite tame in comparison to other round poly’s like Luxilon Alu Power or Silvester Energy or even Yonex Poly Tour Pro.
Final thoughts
Genesis New is a dependable, straightforward string for players who want a clean connection to the ball without having to deal with too much stiffness or launch angles that are hard to predict. It’s a good price, responsive and it’s stable which is especially important for powerful racquets where control is key.
It is not a string for big ball shape and lots of spin. There are spin strings that are more aggressive. If you prioritise control, feel, and value then this is a very good option.
