Perhaps your approach to the back 9 needs a new "offensive coordinator". I'm betting that consciously or unconsciously you're playing a bit defensively to start the back 9 to preserve your score... and get into the 70's.
Go after it on the back side, try to beat your front 9 score. What have you got to lose?
Shot 85 (43/42) Sunday, 11 nGIR/GIR, 30 putts, 2 penalty strokes (both on approach shots).
Started with double bogey on #1 then hot mess of a quadruple bogey on #2, which set the round off poorly, but played okay after that with a couple hiccups along the way.
Full swing is still the biggest obstacle to consistently better scores. Thinned a couple pitches that were costly, but also had three almost chip-ins, so I would say short game was good enough. Still gaining strokes putting.
Strokes gained vs. 5 hcp:
Tee = -0.92
Approach = -6.01
Short game = -1.07
Putting = +0.44
Well, shooting 83 at a 12.7 is a decent round no matter how you did it. With each time you near par, you are showing yourself that you do have the ability to play good golf. My question to you is how did you feel at the turn? A 57 is a serious meltdown.
I'm currently playing Mizuno mp33 blades and absolutely love them when I hit them well. But, I feel like I could do with a bit of help from time to time, and decided to try out a used set of the Mizuno mx23's today. I loved these too but in a slightly different way.
Anyway, I almost took them with me but measured them against my standard length mp33's, and they were all pretty much 1/4inch or more longer. The Pro in the shop said it was because they were graphite shaft (the Exsar Blue) - He said that's the norm.
Bearing in mind I have never played anything but mp33's standard length steel shaft - what difference am I going to find in the slightly longer graphite shaft?
Or should I just wait and try out the standard length with steel reg flex shaft?
