I have the g10 pro irons set and i must say, THEY SUCK!. precision not good at all but not the worst, but, THE SPIN IN FREAKCN TERRIBLE!, I HAVE THEM COMBINED WITH THE TOUR-SD BALLS AND THEY STILL SUCK!. when i first got these irons i didnt notice anything because i went from the starter iron set, but now WGT must ripping people off with these clubs cause what they state is the spin IS NO WHERE NEAR! IT SEEMS LIKE THEY HAVE LOST SPIN OVER THE PAST COUPLE MONTHS!?...SO WHY DONT YOU GIVE ME 1100 CREDITS FOR THEM AND TAKE THEM BACK AND SHOVE THEM....
