If your pins are that close then I think I'd use a single pin adjustable. It allows for adjustments when practicing or 3D and for hunting just set it for a predetermined range (25 yards) and shoot anything between 5 and 30 yards by holding dead on.

The other advantage is that you do not block out the target with multiple pins.

My opinion? The HHA Optimizer series for one of the best you can buy. I use the OL-5000.
