RE: Bowsight recommendations!
Trophy Ridge is the only one of those brands that I have experience with. I love mine. It's 5-pin (I only use 3) and you can adjust it WITHOUT allen wrenches. It's got a cam type mechanism that is a lever you just swing down and then you use another lever to raise and lower the pin. Sounds complicated but its not. I've never had one come loose.
The great thing about archery nowadays is that there is quality everywhere...just take your pick.
