Ok. Tried V/C and VST/C this afternoon in tournament on green set. Sadly only 45mn because my opponent has to retire due to injury in the back..... He has not liked my dropshots.... ^^
So! These two setup are really goooooood!!!

Both strung at 57/53, control is near perfect and I still can have free power when needed. Comfort is so good!! And most important, spin and slice are far better than expected!!!! Not like Hyper-G, of course, but really good!!!
And you know what, V/C is better!!

Now I have to see the durability..... So play and see!!!
