My current load is sighted in for 2 1/2" high at 100 which allows me to hold to 300. Anything further than that I need to make adjustments with crosshair placement. This works much better for me personally than hold over.

However the sight in you chose should match what you'll see in the field. Makes no sense sighting in 3" high if you expect to shoot 0-200! So to steal a fly fishing term you need to "Match the Hatch"!
