I've made a kind of breakthrough since my last post in this thread, just experimenting with different things while practicing putting. I've begun experimenting with Nikko's stance and putting style. By squaring my whole body with the basket (toes, feet, legs, torso, shoulders, head, all facing basket) there should in principle be less left-right error/play since my body is essentially aimed already at the basket. This works quite well, after a good long practice putting session in the 15'-20' range, I'm hitting pretty much everything. Those are, of course, the "must make" putts.
On longer putts in the 25'-35' range the putting style changes just slightly because I need to get a bit more on the disc to get it on a straight line to the basket. Like Nikko I reach back just a little further between the legs and release it with some hyzer. I found that when I go for more snappy feeling releases I was beginning to pull to the right. This wasn't a fluke of my release or anything, it is just the natural direction my body generates more power coming from that position. So instead of fighting it, I'm running with it. For putts 25'+ I line up with my right foot just slightly in front of my left foot (it is a small amount, so even if my left foot were behind the marker it would still work). I can generate plenty of speed on the disc, and it feels just natural and right. In my practice rounds so far I've gotten up to about 50% from 30', which is pretty damn good for me. But then I noticed that I could still square up my feet and my body, and just move my right shoulder forward a bit more in the putting motion, and I get the same kind of positive adjustment. I will have to experiment some more, but perhaps this is just the kind of tinkering around I needed to do long ago to get my putting form working again.
I've also had a breakthrough in the confidence category. I noticed that for a while I had low confidence with my putts and wasn't having nearly as much fun holing out as I ought. So I started to loosen up a bit, go out determined to have fun, and make fun shots, and fun putts, etc., and all of a sudden my confidence was back and I was hitting many more putts than I had been previously. It is an attitude thing. So at least for me, a focus on fun builds confidence.
All this is important for my game because so many baskets around here are on the edges of hills or cliffs, and the ground is hard and the discs that miss are so often rolling away. This really gets into your head. But if you can nail the putt, you don't have to worry about roll-aways.
