I'm sending positive thoughts your way:thmbup:
I've seen the delayed reach-back in slow motion drives from the pros. I found it weird that it was something they did sometimes but not all the time, (so I wasn't sure if I should work on it); maybe they do it more but I wasn't aware of what to look for? Maybe they have such well developed timing that they do it unconsciously to 'clean up' the form mid throw?
Realizing I was leaning back and reaching too far like you describe was a big step forward for me. It didn't translate into any huge gains right away but I think it set the stage for the proper timing to be as effective as it was for me. Nice and balanced the whole way through the throwing motion.
Hips are key. Get that disc moving with a violent hip twist. Don't try to pull it to the front pec, just guide it on account of the hip generated force. The next battle is the timing of the elbow drive. Beyond that I haven't incorporated the 'hammer throw' idea into the sequence.
I found that if the elbow drive is timed right with the hips, that f*$#er is gone! (I may get results with the hammer throw though, just haven't yet at high speed)
For hip rotational speed I work the core with 100 crunches (2x50), 20 leg raises, and some medicine ball work every other day. I take a 6 lb ball and squeeze it between knees, then lay(or is it lie?) on my back, palms down on floor with arms spread out at shoulder height and point knees upward. Rotate to the left, then right without touching ground. Do as many as is comfortable. After a month or so increase the rotational speed of the exercise.
I hear you on the shoulder pain

I think some is normal though. What is normal and what is on account of technique? Or age? Or fatigue etc. ? I use thera-bands and toss the putters first before distance always. Whenever I try to shorten the warm up it bites me.
Thanks for your insights and best of luck.
