If your pins are that close then I think I'd use a single pin adjustable.
ABSOLUTELY! I agree. The pin gap on todays faster shooting bows is so close they just get all juggled up....for me anyway. Cobra makes a great single pin, the King Cobra I, but my personal favorite is the Vital Bow Gear StarTrack. Worth every penny as far as I'm concerned. HHA makes a great slider as well.
