Couple questions here. Been using the KPS88 for a couple years, its served me well but now i want to move to something more headlight. I know the Six.One is the most natural decision but i thought id give some others a shot. Got the Gamma 340 tour really like it especially on my serve. Seriously considering making this the one but then i got curious about Donnay. Do you think I should give their rackets a shot even though i like the Gamma 340 so much? also i strung my KPS 88 at luxilon M2 Pro 16L 54:40, i kept this configuration on the Gamma but is it advisable to change the tension on this new frame? Last question: i have been using the Luxilon M2 for a couple years as well and its been great but i wonder if there are some other new strings that i might like to try that someone might be good enough to recommend? cheers!
