RE: Yes or No for a Sight
I won't use a sight on a hunting bow. I tried sights just once and never again. It cost me an easyshot on a good deer because I got caught in bright sunlight and the deer was in deep shade. The pins were so lit up and bright I couldn't see anything behind them. By the time I decided to cant the bow overto get the sights out of the way and just shoot him, the deer took off.
Over typical hunting distances, say 30 yards and under, I can shoot just fine without a sight. Plenty good enough to consistently get solid head shots on rabbits. I've got to be a bit closer with a recurve, but no sweat with a compound.
I've even won compound class at a local 3D shoot, shooting barebow and fingers against some weak open class shooters (adjustable scopes, releases, long stabilizers).
I always recommend learning how to shoot without sights and put in at least some practicedoingit. Even if you decide to use them, there will be times when being able to shoot withoutsights can come in very handy.
I like the gap aiming method used by Byron Ferguson. Get his book "Become the Arrow." It's written with a traditional slant, but that's no matter. The aiming method is what's important and it's even more effective with a compound.
