:roll: I never had sights on my long bows. I don't use them anymore, but in my younger days I could hang with the big boys and their compound bows as far as accuracy was concerned.
I now use sights on my compound, I also have a 20, 30 and 40 yard pin. I use a range finder and flags to mark off a site when possible, I use three different colors of surveyors tape, one for maximum 40, one for max 30, and one for max 20. It helps in judging distance especially under low light conditions.
