So I have 6 hours on my stock copperhead prop and every bit of the cup has been eaten slap off the damn thing. (Strangely it has lost none of it's diameter

)
Is there anybody out there using an alloy that yields better abrasion resistance? Or maybe a solid tungsten or depleted fucking uranium prop??
I'm open to suggestions on where to find an 11X10 or 11X11 prop that wont wear out so fast.....
