Fastest over hub bowlifting prop out there?

[Toffen]

Hi!

I am doing some research on props for my Phantom 25 with twin Merc 2.5 EFI SS engines. Merc Bravo and Mirage proved to blow out, and the next step is chopper style props. However, it seems to be few props out there for counter rotation. Mazco RE-4 for instance is only RH.

I have found the following brands for twin installation:

Merc ET's
Merc Chopper II
Mazco RE-3
Performance Propellers (Performer 3, Performer SC3, Performer 4, Performer SC4, Performer HP4)
Hydromotive (Quad IV-X OB, Quad IV O/T, Quad IV-X O/T)
Hoss Hyperdrive 3 blade

Which of these carry load best and is fastest (in general).

How does Performance Propellers and Hoss Hyperdrive perform?

Thanks!

Cheeeers, Toffen G

4blade ET's are just down the road.
