I never, ever jump putt. It makes no sense. I'm a noodle arm old man who can easily throw a 175 gram disc 100' accurately with out leaving my feet.
My advice to everyone on putting is the less body movement you have with your putting motion the more control you'll have, a jump putt does nothing but give you power you don't need and takes away accuracy you do need.
I have never been a jump putter, I prefer to walk through my putt if I'm that far outside the circle. I've been that way for the last four years.
They actually cover this subject in the Fundamentals DVD, and they do say its better to have as little movement as possible, and while it does cover jump putting they recommend spin putting or walking through your put rather than jumping.
Instead of using a jump when you are putting from further out try the concept of the step, use your regular putting stance but step with your left leg (rhbh) and fallow through with it. Dave Feldberg explains this in the previous stated fundamentals DVD.
You must release the disc before coming off the ground, so technically not a jump putt, but a putt jump.
See the rule book, and anybody doing the Michael Jordan hang glide and finger roll release needs to be called for a "foot fault, stance violation"
First call is a warning and the putt does not count (in or out) and the putt must be retaken with a proper stance.
Any calls for the same violation during the round costs a stroke for each one.
It's more like a skip putt for me. I try to replicate my staggard stance putting tech. The reason I like it, is because I can still put a minimal to no spin (purposeful) on my disc. So it's the same tech. I use when I'm putting from 15, 20, or 25 feet. I just don't have to keep my feet planted (show control).
I throw a 165 Challenger outside the Circle, I can get that extra distance I need, without the jump putt. I find that I loose a lot of control if I try the jump put. I Solved the problem by throwing a lighter disc.
