As others have said, Bridgestone usually offers a Game Improvement iron in its mix, as in the current J40 series from 2012:
|J40 Cavity Back irons (MPF = 455)||J40 Dual Pocket Cavity irons (MPF = 682)|
The cavity back is a player's iron, the DPC a GI. On the pro tour:
- Fred Couples plays DPC 3-PW.
- Brandt Snedeker plays CB 3-9.
- Matt Kutchar plays CB 5-9.
Bridgestone will mix and match combo sets, DPC on longer irons and CB on shorter irons.
This spring, Bridgestone sent me a Test Drive set for Dual Pocket Cavity:
- a 5i and 9i shafted with TT Dynamic Golf SL R300
- 5i and 9i shafted with NS Pro 950 GH, R.flex.
The R300 were OK, but I really liked the NS Pro shafts better. For both shaft types, the slightly cambered sole really moved through the turf cleanly on iron shots.
The Bridgestones were a bit shorter shaft than my Callaway X20 Tours, so I would probably need a slight staff extension if I bought the DPCs. (I ended up reshafting the X20 Tours with NS Pro 8950.GH, a very similar shaft).
See if you can find a Bridgestone demo day. Spend a half hour hitting the irons to get a better idea of how they work.
Interesting, the burner plus is rated between those 2... I would have thought what I have would be considered like sgi at least....
