I purchased the m455 when they first came out. Loved the clubs but I occasionally pull them due to the offset. Found a set of the m675 (MB blades) and really like these clubs but I tend to lose about 10 yards or so with the longer irons. But when you put a good swing on these babies they are deadly accurate. Decided to try out the m565 which between the m455 and the m675. Love these clubs. Less offset than the m455 and they came with rifle flighted shaft, longer irons get a nice high launch and easy to hit. I am all over the map with hybrids and the long irons in the m455 and m565 are, in my opinion, easier to hit than hybrids and more accurate. I may add the m675 scoring irons to my bag and stay with the m565 in the mid to long irons. I know Mac used to sell a combo set with the m455 in the mid to long and the m565 in the scoring irons. You can find Mac really cheap on ebay.
