I tell ya, I'm not really thrilled with the Speed set up -- i.e., full bed of VS at 58. Just not crazy about it. I played in a drill clinic last night with this stick and my PS Ltd -- which has NXT Tour 17 at 50-48, or 52-50, I forget -- and it was hard to go back to the Speed, although I kept trying. I'm thinking next time around I will try a lower tensioned poly and see how I like that.
Separately, I strung my APGT at 53 with a full bed of Yonex Poly Tour Spin 1.25 and will let you know how it works out after I play tonight.
