As I continue to practice daily going on about 7-8 months now, I feel I have developed an excellent short game. I would even call myself very proficient with my Attack/Approach wedge, which I can hit consistently to within 15 feet from 100 yards...at least in my indoor practice facility in perfect weather & lie. I'm playing with Taylormade Burner Plus irons, where the AW is a 50 degree wedge. With a light, easy swing I'm hitting it with a 33 degree launch angle and a swing speed in the low 70's.
However, as I move up to other clubs, my performance drops. I would say I am pretty good with my nine (125), and OK with my eight (135-140), but after that it's very sketchy. What essentially happens is that the longer the club gets, the more backswing I get, which also leads to less wrist hinge, coil, power, & accuracy. With this long back swing I also seem to use more arms with my down swing.
I can always find my swing by grabbing my AW, but it just seems so difficult not to over swing with the other clubs. My teacher keeps telling me that I should have the same swing for each club, which would be great because I think my swing is great with my AW, but it doesn't seem to work out that way.
This seems to be a mental thing, since I clearly know what I'm doing wrong and I can correct it simply by switching clubs. But yet I still continue to struggle with longer shots.
