If you like the four-blade prop... go to town. This hobby is all about doing what ever makes you happy. What makes me happy is running a two-blade prop that gives me the best performance from my engine. I don't drag my models to the field to set them next to others on the apron and stare at props, I go to fly.

I have a 60 size Top-Flite Sea Fury with a Saito 1.00 and a 15x6 prop. If you and I were to fly together and we did a level pass down the field, the Fury would be traveling roughly 50% faster then the Mustang. If you drop to 3" of pitch it's going to be closer to double the speed. That doesn't sound like fun to me. When I fly with other warbirds I don't want be constantly cutting corners in the pattern just to stay with them; only to have them blow my doors off on the low pass... I want to be with them for the whole loop.

Speaking of reduction drives, I bought this Byron Mustang 3 weeks ago at a swap meet. It has a 24" inch prop with 15" of pitch.
