Thank you all for the info. It is most helpful. The airplane is currently flying with a Props Inc. fixed pitch, wooden prop that is a climb cruise compromise. I live between sea level and about 1500' MSL (Pacific North West). looking for a prop I can adjust for short field and back country flying ans well as cruising to go visit family etc.

I recently heard about a rumored problem with the o-200 and very light weight props causing issues with the magneto drive gear train. I haven't contacted Continental yet but am curious if anyone has heard of anything like this?
Thanks again
