6X HOF
I needed something that offered more launch and little more spin. The J40 is a very low spin head. By talking to the guys @ BFIT they recommended the AD DJ shaft, which is similar to the AD DI but with a slightly softer tip section. The results were good. I was seeing more of a mid-high ball flight and distance was pretty solid. It wasn't the longest driver I ever hit, but during the summer I did find a good groove with it.
As for other shafts I tried with that head. It was pretty limited. I did use a 9.5 degree head with an Attas shaft for a few rounds last December. My swing wasn't all that good that week, but on balls I hit well I could see a benefit for that shaft combo.
thanks for the info, after trying the AD-DI7 in the extreme this weekend, I really liked the way it felt and would be interested in seeing how it would fit in the J40
