So much more goes into a jump putt/putt jump/jordan putt/whatever putt that it does seem like there are too many variables to control and be consistent. I've found that when I have to go long and don't want or need to stand balanced and throw...a walk through putt seems more consistent.
You're wrong. I cannot propel a disc 100' with my traditional spin putt stance...I top out around 40 or 50'. With a spin putt I can get it out to 80 or 100' ft. But from 40-60' is where my jump putt shines. I have to swing my arm so hard with a trad. putt from that distance that I don't hit hardly anything, but jump putting in that range I make a lot of those putts, probably around 40% on a calm day.
For those that say there are too many variables that can throw your shot off jump putting, again, I say you're wrong. The thing that's great about a jump putt is that it's all in your legs. It allows you to use your normal putting while you utilize the springing motion. With practice, it feels totally controllable. At 100 ft, I am more consistent where I land the disc than throwing. I use it all the time to lay up.
If you don't want to jump that's fine. There are people who are blessed with a physique that allows them to trad. putt from long range. Just don't criticize the style because you don't use it or never took the time to learn it.
If I'm outside of the circle i use a step through for putting. And even then my distance putting is not all that good so i normally just try to drop it as close as possible, because jumping can put to much elevation on the disc and cause you to miss.
