Lots of really good idea’s here. I’d like to 2nd them all, especially the question about weight. If you are shooting a trad bow in the same weight range as your compound, that’s a formula for failure.
Move up, shoot a lighter bow, don’t shoot too long, drink a beer, and have fun. It’s supposed to be fun. And it is fun.
That said, I have felt the frustration caused by bad shooting. There is no magic cure or cookie cutter solution. Every person has to work through it their own way. Good luck and I hope you stick with it.
And contrary to what some of the experts say, we can’t all be as good as howard hill. But I do think we can all get good enough to kill a deer at 10 yds.
