Duc...I guess I'm old school...I started with a recurve in the late '60s...I could hit a paper plate at 25 yards, killed several deer with that old Bear....I have never shot at a deer past 25 yards, I set up for closer shots...Ask yourself, how far have you taken a shot at a deer? I can see if you are hunting antelope over a water hole wanting to shoot 40-50 yards, but down here in NC, I setup in the white oaks and wait until I have a perfect shot...I use two pins, one set at 15 the other at 25, I shoot fingers and have never used a peep...Alot depends on your hunting style and your approch to bow hunting, to me its the challenge of getting a deer within 25 yards...
