RE: What type of sight do you use??
Whatever you choose make sure it doesn't have any plastic. It'll last longer and give less troubles along the way. HHA OL 5000 is a very good one. One other thing to consider is that someone is lying through their teeth to you. There is no bow made that can shoot a single fixed pin out to 50 yards. Even with a sight setting of 25 yards you'll see about 3" drop at 30 yards. At 50 yards it'll be about 2' drop.
