The HHA line of sights are great. I hunt with a 5500 Ultralite with the rheostat feature. You will love the clean sight picture a single pin gives you.
Like Chuck said, sight it in @ 30 yards or so, and you don't have to make a lot of adjustments come crunch time.
I have mine zero'd @ 28 yards. I am an inch or so low @ 15 yards and 5 inches low @ 40.

Heard good things about the Anchor sight as well as Perry's no peep. I wish there was a decent bow shop close so I could try one out. I would hate to buy the dang thing and not like it.

Good luck and I wish you clearer vision in the future!
