Fast forward a full year++ and I have tried dozens of combos of strings on my two matched frames. Even tried switching to a Blade v8 18*20 at some point. I found the one thing that absolutely undoubtedly always works best (though is a waste if you use it in humid weather as it gets ruined too quickly) and it's so good that I think I may never leave the v13 for as long as I play. And that, to no surprise, is VS Touch 16 mains @26kg with Alu Rough 17 crosses @24.5kg. not a budget setup but having tried many poor man's versions of this, nothing even comes close to the magical feel and precision and power you get.
