I really like the BlakeT short arm putt technique. I tried using it exclusively about 6 months ago, and I had some good success with it. My problem was that I could never get consistent with my release height. I would always be dead on the pole, but from the same spot and what felt like the same putt I'd be all over the chastity belt and front rim. It was a useful exercise thought, as a lot of the principles have been helpful to work into a more push put style.
