It's a trade off with a fixed pitch prop. Particularly on airplanes with as wide of a speed range as the RV's have.
You could re-pitch to allow you to use full throttle at 8000 and you will really scoot but I think you would be unhappy with the takeoff and climb performance.
My personal preference is for a prop pitch that gives about 2600-2650 rpm with WOT at 12,500 ft. This will give you a pitch for goo all around performance but it will require you to throttle back some at lower altitudes.
