Casey 1988
Shun the frumious Bandersnatch!
The best improvements in my putting came from trying out loads of different styles and working out what worked in each and then trying to put these all together. Before that I could practice putt all day long and see no real benefit on the course. Now I know what my body should be doing to produce a good consistent putt and can practice putt far more efficiently. It also means I feel comfortable going from anything from a straddle to a turbo putt which all come in useful in tournament play.
It is more translatable to the course as all I need to do now is work out how to get my body in balance before the putt. I do that and it should go in. My misses are high and low now hardly ever left and right. I still have a mental barrier to overcome in the 20 - 35' range where i hit the bucket far far too often, but inside and outside that my putting percentages are way up, my circle 2 makes are well over 1000 rated even when not practising, to the point I sometimes consider trying to land further from the target as I'm more likely to make the longer one. Mine is a commitment issue in the 20 - 35' range, outside that I go for it inside that I go for it. in that range I suddenly find myself full of self doubt and putt low.
You know those putts you just know are going in before you take them? I'll bet it's because your body is properly balanced and ready to go and you just haven't realised all the times you aren't. I'm finding that feeling more and more in the long putts now when I feel my body is set right pre putt.
In terms of practising putting, never take lots of putts from the same stance, putt, move a step to your left, putt again step back to the middle, putt again step right, then forward etc. This means each time you have to get into balance again, you're not already there. It teaches your body the most important bit which is the set up.
I'd highly recommend that your practice putting tries out all styles of putts not just the one you are comfortable with and use on the course. This is practice to better understand how your body works rather than repeating actions.
I know exactly what you mean, I had used a bunch of different putting styles and can go from my slightly different most but my normal putt, to a from the chest spin putt for wind up to 27 mph, and a forehand putt for low ceiling shots. The only putt I can not do is a straddle putt unless I have a high glide putter like a Areo or Rubber Putter type, a lid of some kind, Sonic/fastback mold or a lighter weight putter under 169 grams I have trouble generating the power for a straddle putt.
