I have to concur on all accounts. I use a 32x10 Biela on an old 3W 140 and like it the best of all the props I've used on that particular engine. It spools up nicely and gets around 5900~6000 which is good. It is 31 7/8" long and weighs 13 ounces.
You owe it to yourself to try a Biela if you can, although it's not like a .60 where you can haul around a half dozen props at a time[&:]
Oh well, that's the price of progress
