Have you CO guys talked with Matt over at Rockware?

I know they do custom fab stuff for Rovers and Yotas. (I used to have some of their suspension components on the D90)
He might be a good resource and they do have a rockcrawling focus. It seems like the potential customer base for H2s is large enough to justify some $ for R&D (on his end).
I'm interested in something better too. My frame rails are not too purty these days.
