I've been using the Prestige Pro, both YouTek and IG for half a year now, and I intend on playing with them until they break. The only tinkering I've done with weight is just matching the weight and balance of two of them to my third, and favorite.
For strings I hit with 16l gauge poly in the 40's, unless I want to splurge a bit and then I string gut/poly.
For clothes I'll wear whatever, although I get shirts and shorts for playing club tennis. For shoes I prefer the barricade line.
All aboard the Gulbis bandwagon!
