As i have commented in your other thread, i´ve experienced a similar situation about the QC.
I´ve played a variety of prestiges (fxp´s, mg´s and youteks). The youtek MP was the best (a bit stiffer, but with a great crisp feel). Sadly, i wasnt being as consistent as i needed and my arm was suffering a bit the stiffnes.
By pure luck i´ve bought 3 C10 Pro´s from a guy i know.
With this particular racquet, i´m getting a great experience, i´ve raised the tension about 10lbs because is more powerfull (i used the prestiges in the high 40´s and i´m using 60lbs with the c10) and i get the same control, but in a more comfortable pack.
Spin is about the same (i´m comparing it with the youtek mp) and also the swing speed.
