II have a 16x8 MAS 3 blade prop but I think it might be a little too much, although it does have a tremendous amount of pull.
I can tell you that a 16x8 MAS 3-blade prop will be too much. I also have a Saito 150 in mine with Slimline inverted Pitts, and it spins a 16x8 MAS 2-blade prop at only 8400 rpm. My guess is that your 150 will spin a 16x8 3-blade at around 6700 rpm, which is way below the engine's power band and not healthy for the engine. I'm thinking about replacing my 150 with a YS 120FZ.
