I have 2 New Years resolutions...play more golf and lose a few pounds. So I decided I want to start walking to enjoy the game and burn some calories. One question for you guys that walk, how big if a difference does 1lb of bag weight make over the course of 9 or 18? I like the Players 4 Carbon, Players 4 and Players 4 Plus...with the weight increasing with each of those models. So if I like the look of the 4 Plus how much more comfortable would walking with the Carbon be based on the weight difference? I appreciate the opinions!
