I've used a 24X10, a 24X10 cut down to a 22X10, and a regular 22X10, all Zingers. All worked fine. Turned between 6000 and 6500 on the ground. Problem you'll have regardless of what prop you run is keeping front bearings in it. If you notice the idle increasing with no change in the carb/servo position the front seal is leaking air into the crankcase. This sucks all the oil from the front bearing. Original seal lasted maybe 40 flights. I went thru 6 seals and bearings in a year.
