I can tell ya one thing. When you start trad shooting, espeically heavy bow, it feels very uncomfortable for a while. But after a few years of doing it, going back to compounds hurts.

See with a longbow or recurve, your force goes steadily up. By the time you get to full draw, all the wieght should be on your back. But with a compound, (especailly new ones), you could be pulling 70lbs at middraw. Even though there is letoff, it could feel strange.

I shoot my trad bows about 2 times a week. I may shoot my compounds once every 2-3 months.

I haven't had one affect the other really.
