so i was thinking about getting a titleist 690mb, but my friend said that i should try and look at all the other forged irons before going for the 690mb. so i was wondering what other forged irons would you guys recommend?? also what is the difference between mb and cb?? i know mb means muscle-back and cb means cavity-back, but what is the difference in performance? i saw 690cb's for cheaper than mb. thanks
