Anyone out there hard on props?

[Wild and Free]

I have several friends who boat on Audubon lake a lot and pretty much every one of them either destroy a prop or two a year or destroy a lower unit. I came across these props while on another boating forum and thought I would share the info in case some may not know of it, looks like the perfect solution to some of the unfortunate ones who can't seem to learn or refuse to get decent Sunglasses like Costas where you can see the rock and gravel beds before you plow over them.
They make plastic props with replaceable blades.

Years ago I wrecked a few on Audubon. That lake is a mine field. But, im just getting back to fishing Aud and taking my time mapping safe routes on the gps.
