I like 7-pins, sighted in 20-80 yards, in 10 yard increments. I practice at all ranges in the gaps between the pins. When I know the distance, I only need to draw, aim, release--no slider/dial adjustments required. When a buck or bull suddenly sneaks in or suddenly runs into a shot opportunity, I'm ready for that moment.
This sight system has been a huge advantage for backcountry horsepack elk hunts in Idaho. With fewer moving parts, there's less to go wrong, and less mechanical parts = lighter weight sight and total bow weight for steep climbs in rugged country where 12-15 mile hiking days are common. Over the years I've seen a couple of hunters in our elk camps get their hunts ruined by getting their fancy slider/dial type sights damaged by the perils of mountains and horses. My fixed sights tend to be more durable than adjustable sights.
I've occasionally considered setting up an adjustable on one of my bows, for longer range shooting practice, but I've gotten so used to fixed sights, I just use them for all hunting and shooting. I really have no need to extend my range beyond 80 yards anyway, and I'd sure never think of shooting a whitetail at that distance.
