You are on the right track - and at 22-23 lbs this thing really changes performance -
your change is on the order of 1/2 tank of fuel -weightwise .
for best vertical performance - go to smaller prop - try a 26x10 Mejzlic - let it rev
it does not matter what the engine is - larger quieter props are not as good at verticals -
IF you have an engine which will swing this prop at close to 7000 you will see very good verticals.
