I only deal with Lowes, (personal reasons) and I have them cut plywood for me.
I give the guy the measurement(s). They set the saw, we check the measurement again, and then they make the cut.
The first few cuts are free. Aditional cuts might be $0.25 each.
I can't throw around full sheets of plywood like I use to do. (I can in a pinch) Having stuff precut to fit, works out quite well for me.
I replace virtually everything about every 5-8 years. Usually the set makeup changes when I change things out. The soonest I've ever replaced an iron set is after about 3 years. Drivers as often as every 2, but I've used drivers for 6-7 years also. Putters....don't get me started
Just read through this whole thread, great topic and a lot of helpful advice. I have yet to shoot under 80 but its a goal of mine.
I agree 100% with the points about the long game being more important. I only got a handicap this year for the first time its a 17 at the moment and the only way it will drop is if I start finding fairways and striking irons a lot better. My short game is fine, I very rarely putt more than 36 times a round and my play around the green is solid i think, but its my long game by a long way that needs the big improvement if I am to break 80.
