It seems that all of the pros have gone to a kind of over the shoulder, side arm, type of stroke for jump shots. This started about 3 years ago, maybe? Now, virtually all of them are doing it. No dart stroke, no underhand stroke, even for full length shots. I tried it for a bit, and it seemed really awkward. Difficult to get any real acceleration. Watching the recent big tournaments, they are all using the same stroke, with excellent results. Why the change? How to execute?
