I'm looking too.
Ever since I Got a set of 5 blades,
I keep wondering what the'll do for it.
The 5 blades really hook up.
( I don't know if the boat even has to be in
the water to make it move, with em on

)
Tres Martin had a pair of cases in the
classifieds last week......they were gone
in an hour.
I'd pay decent $$$ just to rent a set to see how they work.
