A Bridgestone ballfitting team showed up at my club in mid-July. Besides balls they brought some irons with them.

I hit a 4i, 6i, and 8i in the J40 Dual-Pocket Cavity - shafted in PX 5.0. This model seemed to move through the ball quite well. I have the same shafts in Callaway X20 Tour, and the J40s seemed a bit livelier going through the turf.

I also hit a J40 Cavity Back 6i shafted in PX 5.5, and it seemed to feel about the same with a similar launch.

What is the difference supposed to be between the two models? Both are forged from 1020 steel, the CB has one degree higher loft in the upper irons, and just slight differences in bounce and offset.

Both are pegged for pro to mid-hdcp amateur golfers.

Any views on the performance difference between the models?

Focus, connect and follow through!

IMO, the dual-pocket is a bit more forgiving because of the pockets that are milled out of the cavity.  It moves the weighting a bit lower and to the outside, helping to minimize the effect of mishits.

Both are great irons, its more a matter what you prefer: a bit more feel or a bit more forgiveness.  Bridgestone really is one of the more underrated club companies out there.
