Wow, a lot of good advice there. Thank you and by the way I'm from Denmark so it's actually velkommen
I was actually throwing for control, so my body positions should reflect that somewhat though your advise probably also apply to my distance throws. I know I have trouble turning my back and head all the way against the target, so I'll definately work on that as well as my arm pull angles and acceleration point.
I think you are right about my thumb, as I've been having some problems with rolling over my wrist which is really messing up my timing leading the disc to turn over. Is forcing the wrist down during the throw the best fix here?
