I once ran some Manitou X-verts on a Santa cruz Chamelon frame,looked rubbish though.If you're gonna put some on a hardtail just make sure the frames strong enough,like the Sante cruz.
Personally, go for a long travel single clamp fork. I had triples BITD and have really gone off them. They look naff and there is only a really small market that want them now, should you ever decide to sell them on.
