Coming back to compounds after about 10 years of solid longbow shooting, my biggest shooting problem was not being able to see more than a blur where my pins were supposed to be. It kept getting worse so, rather than try to learn to shoot with reading glasses, I took the sights off. I used to shoot barebow compound in competition some, back in the 80' s (NFAA Competitive Bowhunter class). Now I do it full time. Still pretty decent at it too.
