what prop do you have now??..the main thing is to make sure your not out of spec. when wot...wide open throttle.....you should be about 4200-4800rpm...if you change prop and are out of that spec...then your defeating the purpose....so...with that said...1" pitch change will change wot by 200 rpm either way...so..if you have a 21" pitch prop..a 4600rpm and change to a 19" pitch..that will drop you to 5000rpm and your out of WOT spec.....but the change will allow you to pull a bit faster on the plane.....so...you have to weigh it all out.
do you have an al. prop or stainless steel.??...stainless will flex less..give better bite....better response...
