I run a six pin MBG slider. I can practice at long range and not have to worry about moving my sight when hunting, it is the best of both worlds. There is absolutely no way I would consider having a single or double pin slider for hunting, that is just way too much to mess with when a shot presents itself. And really, since every pin moves on a slider you can still dial a multi pin setup to a relatively precise yardage. If I have a 45 yard shot I can slide my bottom pin (the one that the tape corresponds to, 70 in my case) to about 73-74 and my 40 yard pin is now set for a 45 yard shot. I rarely do this because gap shooting is way quicker, but it works if you really want to hold a pin directly on target. It's a trick I figured out a few years ago, although surprisingly I've never heard of anyone else doing it. The only thing you have to consider is that the gaps between pins gets progressively wider at each 10-yard increment, hence moving the 70 down to only 73-74 for a 45 yard shot. So for a 65 yard shot I'd move my 70 to 74-75. And I pretty much always gap shoot 20-30 because the gap is minimal. It isn't perfect, but gets your pin within a yard or so of perfect.
