Welcome! I am new to trad equipment after 20 years of compound shooting and I am having a blast. There are some great guys here with tons of experience and great advice. I would offer this, keep in mind I have been shooting trad for all of 2 months so take it for what it's worth.
*Get a bow that you can draw comfortably
*Find a comfortable and consistent anchor and hit the anchor on every shot
*Get your nock point set and arrow spine, tip weight somewhere "close" to where it should be... If not you will spray arrows all over the place...
*Now for aiming... Again I am not the expert... Make yourself pick a spot and focus... This sounds easy but its not... This has really been tough for me, at first I was focusing on a general area and not a spot. "Focus on a spot, a small spot"
*After somewhat tuning my bow, finding a consistent anchor, really focusing on a spot and pulling through my shot, I am actually getting respectable and enjoying myself... There is certainly more to trad than I have mentioned, however this has helped me consistently hit the target with fairly decent groups for my short time with trad equipment... Good Luck!
