My putting is extremely tempermental. Sometimes it's really good and 10 footers look like tap in gimmes and other times I am literally stressing about two putting from 15 feet away. Over the course of this golf season I have changed my putting technique many times based on articles I've read in magazines or online, tips from other players, pretty much anywhere and what I've noticed is that regardless of what the change is, my putting tends to improve immediately for a few rounds and I think I've finally found the secret to putting and then, sure enough, I start putting terribly again and the cycle restarts. Some of the things I've tried this season are:
1) holding the putter very upright ala Steve Stricker
2) standing very tall
3) bending over quite a bit
4) various degrees of forward press before the back swing
5) slightly open stance to see the line better
Surprisingly the only thing I haven't really trying a left hand low or other style of putting grip. I was wondering if anybody else had similar experiences, basically if you were struggling with your putting did the simple practice of changing something (posture, ball placement, alignment) help, allbeit maybe not permanently? Is it good to switch it up every once in awhile if your putting starts to suffer or is it better to hit the putting green and practice some tried and true fundamentals?
