I hit these with the uniflex shaft in them, which didn't suit me. I felt like I had to speed my swing up to feel the ball come off the face. I didn't try them with a different shaft though. So I would massively recommend getting fitted properly for them, (the shaft is just as important as the club head!).
These Callaway x-22 irons that I bought last month from www.golfsales365.com are the best irons i have ever used. The shaft didnt bother me at all in fact i think it helped me. I used to have titleist ap2 but found them very unforgiving nd hard too use and the seame with the ap1's. I also tried out taylormade burners but found the shaft too long and heavy and the power You get did not make up for the poor control. I reccommend callaway x22 at golfsales365.com to golfers of all levels preferably 18 lower
Maybe some golf beginners would ask, How should a relatively new golfer know what kind of shaft is suitable for him? What should we look out for during the swing which determines the appropriate shaft? The only way to truly know what golf shaft suits your swing type/speed is to get on a Launch Monitor with a trained professional. There are so many variables that work together; it is very difficult to do it unless you have a trained eye. My advice would be to find a professional club fitter and set up an appointment to get fitted.
I know that golfsales365.com can provide the guide for any one who would like to buy a golf club or would like to play golf.
