Still in love with my 2021 Gpro! I am currently experimenting with different strings. Really enjoyed Head Sonic Pro 24kg and now i have finally tried natural gut (Babolat VS Touch). I decided to take it step by step and not try it in the mains first, because i value control the most. So natural gut in the crosses 24kg and Head Hawk Power 23kg in the mains. Played one match so far and liked it but needed some time to adjust to the new feel and response. The only downside is that it increased the static weight of my racket up to 2g and funny thing that i always feel this 2g difference in my Gpro where i love it when it is 330g (no more, no less) but 332g already feels a bit slower and more cumbersome.
My next step would be to try natural gut in the mains and head hawk power in the crosses, so a reverse set up. And then i have lots of strings on my list that i would like to try in this Gpro: Head Hawk Touch, Kirschbaum Evolution, Kirschbaum Max Power, Tier One FireWire/GhostWire in a hybrid, Volkl Cyclone, Solinco Confidential, Tourna Big hitter silver, CyberFlash etc. Mostly round strings as i value control in my game and shaped strings could be quite erratic for me.
But i also wonder if you guys tried a good natural gut/poly set up. I have seen NG/4G, NG/Element. Anything else you could recommend in this fantastic frame?
