Speed is generated in part by muscle. There's a very large part that is form that either hangs us up because we don't connect all the pieces well, or everything links together and our core muscles sync up with our arm at the right moment to give maximum acceleration. Being flexible and coordinated is more important than the power behind the muscle, but at least some power behind the muscle needs to be there.
Exactly what I'm getting at... I know I throw much better now, the appropriate discs and form tips and just information in general has greatly improved my game. The idea that "regular" dudes could throw a putter 300' or even 150' was a revelation.
Getting a putter out to 150 is fairly easy for me, even if my form is out of timing, or my back is messed up and it's an all arm shot with zero lower body.
The sidewinder is a very acceptable disc to underpower. Roadrunner, leopard, relay, etc.. Just not xcal and destroyers. I do play with a guy that flick putts a star 165 beast... I tried giving him a Buzzz as a gateway "putter" haha. Guy still nails it in dubs and I think he's the ace leader for stats this year....
