I made some skis from aluminum for a cub once, but never got around to trying it out.
I'd be curious to see your ski configuration.
Do you have a close up photo of how you built them?

Mine were spring loaded to prevent the tips from going toe-down.
And I had a pre-cut tube that each spring was inside of so that they woudn't be too much toe-up either.
I always wondered if they'd have worked.
