We have seen enough composite props [like Pirhanas] break blades for no apparent reason that we do not recommend them other than an emergency spare and still would rather see aluminum cause they are more efficient .

Marc,
Is this true in the lower horsepower motors (under 100HP). I found the performance to be a little better with the composite but it is also a little bigger in Dia. Also I would have to compare it with a new aluminum prop. which for me seen to attract the bottom. However the main reason I use a Piranha prop is because they do not cost as much to repair.
By the way you sold TOGO to the person I bough her from thanks.
