I have one of the Cosmic Lite single " sliding" pin sights from Impact archery.
My bow is pushing close to 290 FPS, and I have my pin set at 25 yards. I' m only about an inch low at 30. I also have a " mark" where to set it for 45 yards, but I only practice at that distance. I prefer to keep my shots under 35 yards. At 35 I just have to hold a bit high to put one in the boiler room.
Even when I shot multiple pin sights, I only liked having 2 or 3 at most. I prefer using one..much less confusing in the woods when my nerves are shot. I see some guys with 4 to 6 pins, and I wonder how they ever choose the correct one at the heat of the moment. That would be too much brain overload for me...and it doesn' t take much
