and the max master and max 80 are the same putter i believe as far as their attributes. I think the main difference is the increments. I have master and they are in increments of 10: 10, 20, 30, 40, 60, 80, 100, 200, 300. I think the 80 is more increments of 15 I don't know exactly tho. So between those two its just a matter of preference on how you putt. Do you like to calculate percentages or do you use the movements of the avatar to putt.
