Hey,

play the 712 MB's with project x shafts and I love them 3-pw. And 910 H 19degree, 910 f 15 d, 910 D3 .

Love them all. The irons feel great With the shafts. I played the 690 MB's for ever them changed to 695 MB's. had them since 2006 then finally changed to the 712's

I've got the 712 MB's and they're probably the best blade I've ever played, and one of the top 3 irons I've ever hit.  As of now, I really don't think I'll switch to the 714 any time soon.  I don't see the need to.  In fact, I'm considering picking up a second set off ebay, just to have when this set gets too beat up.  

Definitely hit the MB's and even the CB's.  I think they'll be a good fit for you.  

Thanks guys really helps!
