RE: single pin vs multiple pins
I use a single pin slider.... never going back to multi-pins.
I am only (haha... only) shooting about 280fps. So I don't have, no believe I'd want to have ONE PIN to 40 yards... my line of set up and thinking is that I leave the thing on about 25 yards or so.... and I can kill a deer with no holdover at all out to about 30.... I need to put the pin on the line of the back at 35.... and if he is farther than that... I probably won't have a shot.... but I'll take the time to range him and move the sight.... if he moves.... well ...... thats bowhunting.... its about how close not how far.
Thing I like about the single is the sight picture is exactly the same everytime. I had a tendancy to move my head with multi pins... which is cool.... so long as I did it the same everytime. I've found myself to be much more accuracte than I was before with a single pin.
