I think M10 has been in the works longer than restring the company as a whole
Yes, I think you're right. ReString says in its website it was funded in spring 2020 and started the research and development of his first string in winter 2020, which was released fall 22. Other user here says he was getting M10 prototypes already in 2020 (I believe back then it was called Confidential 3.0). Also, I think I read or heard somewhere (maybe at Solinco's own website, fow what it's worth) that M10 has been in development for 10 years.
So, could it be Zero is actually a rip-off of M10/C3.0?
Was C3.0 already in development before C2.0 (standard Solinco Confidential, if I'm not mistaken C1.0 was the codename for H-G when it was in development), which came out Jan 20?
If so, why the change to code name C4.0 / unreleased 4.0 if it's a development of the same project? Just curious.
And how a new company managed to develop a string so similar (imo) to theirs, or at least that good, in under 2 years of development? Maybe RS was funded by Solinco former members/spin-offs with inside knowledge on C3.0?
Is it that Solinco spends a lot of time in testing with pros and sending samples to get feedback? Because these new brands seem to be releasing almost a string a month sometimes (imo a little excessive) like Toroline, several a year like GS, or at the very least one every other year like RS.
Honestly, I don't think that it is an attempt to match Restring Zero- M10 doesn't have the slickness or the power of Zero, and Zero is a lot more muted and less controlled.
Well it seems it was already in development way before Zero, so probably not, although I'm curious why the change in codename from C3.0 to C4.0/UR4.0.
I haven't had the pleasure to try C3.0 but UR4.0 definitely felt as slick as Zero (or very close) to me, and hence as spin loaded. I can't be totally sure about power, I remember Z surprised me because I was expecting a stiff string when I first tried it and it felt super powerful and spinny, but when I changed to 4.0 (same as the released M10 I assume) the Z was already playing acceptably but very notched, not as spinny, and probably a little loose. The M10 was definitely strung tighter because it was a thinner gauge, and I felt like it was a little less powered because balls were dipping fast but a little shorter than with Zero. I was unsure though if that was just a product of old Z putting less spin and adding more SW to the racket (it was close to a 3 gram difference iirc). It was all very subtle and the comparison wasn't perfect, but if I had to say anything I'd agree about the power, not about the spin/slickness.
I'll try to test them back to back as soon as I get some M10 16g
