Just received my set of irons (4-AW Reg Flex Steel). My previous set were the TaylorMade Burner 2.0's and I usually would shoot in the mid to upper 80's. First round with my new RBZ irons, I shot a 79. These babies are so sweet to hit and they are STRAIGHT. Good feel, very forgiving, and about 7-10 yeards longer with each club over my 2.0's. If you are looking a great set of game improvement irons, that are easy to hit, I would highly suggest that you give these a try.
TaylorMade offered this entire set with conventional irons, and you didn't already own TM Burner 2.0 irons. From 6 thru wedge, these are quality irons, but they don't appear to be appreciably longer than my 2.0s. The "metalwood" long irons don't fit my eye, but they will go a long way if struck properly. Recommend that unless you're truly looking for "super game improvement" irons, either look at the Burner 2.0s or consider a 6-wedge RBZ set. I replaced the 4/5-irons with those from my Burner set. The hollow metalwood long irons are probably overkill for 12-15 handicappers and below.
these clubs are great i am a 11 handicap ipicked up 15-20 yards per club i get a lot more roll after they hit the ground not to thrilled about the hybrids 3-4 it hit the regular iron just as far i love them
