Control over direction was the main selling point for me. I have a medium speed swing and went with the R-80 shafts.
I compared the Taylor Made with Cleveland Launcher and the Fat Shaft Wilson and found it superior in forgiveness and distance (10-15 yds longer) than both these clubs.
I have no complaints at all with these clubs and hope to use them for many years to come.
I recommend people try out various clubs at their local range if possible before they buy. A certain amount of confidence comes with knowing I've tried other comparable clubs and picked the one that felt best and worked best for me. No wondering or what ifs.
