Yes, you've hit on the other problem I suspect I have.
I'm working on getting the weight forward, etc., because I can see it in the mirror or the video. And, also, nose up has always been a problem and getting to the front leg helps that. I spent a half hour this morning throwing putters at the soccer field and I was getting much more nose down and farther throws with less effort. It felt so good I quit early before I lost it (superstition). But 200 seems to be my limit with an Aviar. 250 or so with a midrange, I throw mostly Leopards. I'm 5'10, 135, in my 60s.
I have a relative who does not seem to get any weight transfer or body into the throw, it's more of a forearm flick, but her distance is close to mine. I conclude she's doing the wrist or pivot or something correctly. I've tried to catch her on video but she always evades.
