I shoot a single pin slider. Seems like out in the open spaces that I hunt in most, my shots are often 40+ and always have time to range my target. I like to put the pin on target, without holder over/under and at longer range, it works great.
When I'm back on the farm in KS. hunting whitetails from a perch, I set my pin at 22 yards, and anything that walks by will be in range and good to go, because for the most part, I won't get a shot longer than 30 yards.
