If its 1.25 gauge than it is difficult to hit spin with that string. Otherwise i would suggest babolat rpm blast however i dont like the high cost of it.My buddy prefers poly tour pro with his.
edit: he strings it @ 48 lbs. Solid 4.5 counterpuncher/baseliner with flattish strokes.
I was told that hyper g does not work well in the vore pro 97I love my Vcore Pro 97 and feel like it plays well with almost everything. I usually play with a gut/poly hybrid (VS Touch in the mains and ALU Big Banger Power in the crosses at 54 and 49 respectively). I also love a full gut setup with the crosses about 5 lbs lower than the mains. My son has his set up with RPM Blast at 54/49 and it plays quite nicely. I just strung up Yonex Poly Tour Fire 17 at 53/48 and like it enough that I think I'm going to move to full poly. I ordered some Hyper G as a test. Really love the racquet and haven't yet found a string I didn't like in it.
