Solinco Mach-10 String

Solinco has released a new string called Mach-10. It is a softer, five-sided polyester string supposed to give you a mix of power and spin.

The Solinco Mach-10 string comes in four gauges: 1.15, 1.20, 1.25, 1.30. You go thicker for more durability and control and thinner for more power and comfort.

You might have tried Solinco Mach-10 but under the name of 10jx or Confidential 4.0, as this string has been developed for several years. According to Solinco, it is their most technologically advanced string to date. Mach-10 has something called CloudFORM, which is a unique chemical agent that softens the string without limiting the playability duration.

For now, Solinco Mach-10 is available in a fresh blue color, somewhat similar to the Tru Pro Pure Rush and Restring Zero. Maybe there will be more colors in the future.

Solinco Mach-10 Review

I have tested Mach-10 in various racquets over a few weeks. It is a lively string, but still offers that dip-in-at-the-last-second functionality that we all enjoy with polyester strings. I was surprised by the snapback the string provided, because I usually find softer strings are diminished in the type of spin potential they can provide. The string is still powerful and comfortable (for a poly string), so if you are a fan of Tour Bite or Hyper-G for their excellent control and prefer stiffer strings, this is not for you.

I tend to belong in the stiffer string camp, so for me, Mach-10 worked best in low-powered racquets like my Prestige MP 2019 or the Solinco Whiteout 305 V2. When I put it in the Solinco Blackout 300, I felt like I got a little too much power for my liking.

But if you are looking for a slightly softer poly string that retains the playability aspects we like in polys, I think Mach-10 should be on your list. It has a nice impact feel, still somewhat crisp despite being soft on the arm.

If you have arm issues, I would still consider multifilament strings instead of a softer poly unless the poly is really soft and you go low in tension. But for players who are in the soft poly camp, Mach-10 is an exciting new offering from Solinco.

This string holds tension better than the other softer strings in Solinco’s arsenal, like Tour Bite Soft and Hyper-G Soft and I think it has a more pleasant feel on impact.

There is a lot to like about Solinco Mach-10. If you are looking for a softer poly, give this one a try.
