Bill,

My experience with the 3-blade props on the Twin Air and with the Saito 200Ti on my Mustang is what is driving me toward 150's. The 2-blade props on my Twin Air are fine- its "just" a sport plane. But I want to be absolutely sure that I will be OK with 3-blades on this one. And the Saito 200 is a recommended engine for my Mustang and it flies the plane just fine, but there is not much reserve power. I don't like flying with the throttle wide open! If someone could convince me that the 120's would give me adequate reserve then that's the way I'll go. I'm just not convinced, yet.

180's? I think now we are talking seriously "over-powered". Not really my goal.
