If I had to guess, Dan....I'd say you were having trouble drawing your bow with your hand in the proper position.....because you're pulling too much poundage.
There's nothing wrong with cranking it down a little. No shame.
If my son (he's 14 but looks to be about your size) can't put his sight pin on his target and draw it straight back.......I turn it down.
If I'm wrong....I'm wrong......but it's something to consider.
I would agree this could very easily be the problem. I am a pretty big guy (215 @ 6') and 70lbs is a bit much for me to maintain good form when I am not shooting a lot and conditioned well.
The proper hand position before the draw is critical becauseit will prevent you from inducing torque into your bow arm during the shot sequence while trying to get into a proper grip. Once youadjust weight and learn how to set this before the draw, and then learn to hold the tension needed to maintain form in your back,your front arm can be amazingly relaxed and it will slow your sight picture movement
waaaaay down. I actually take the time to visualize this relaxed state of the bow arm before every shot as part of my shot sequence, I can't imagine trying to adjust it at full draw while trying to maintain that shot tension in my back, next to impossible IMHO.
