Virtually all APC, so will vote that way, but recently tried some Bolly Clubman props, and was impressed with them.

Basically, APC do so well as the props are stiff and well designed, making them efficient, and they do such a big range. Bolly Clubman are a far smaller range, and the main Bolly props are dificult to get hold of in the UK, as well as being v expensive (not that the big APC are that cheap).

I wish both did more 3/4 bladed props.
