I'm installing a Catto 3 blade prop on my RV9. To keep my weight and balance where I want it I need to add 12# to the nose. My choices are to purchase a 15# crush plate from Saber or to use an 11.4# Landoll Harmonic Balancer which I already have. Aside from the obvious economic reason is there any other reason I should not use the Landoll balancer?
