Panasports, anyone??

Exactly. For those realy interested it is worth looking at each product line within each of the brands. While they all look similar, there are solid cast versions as well as multi-piece and super light wieght models.

I notice they have solid cast and bolt on cast ones. But thier website is very lacking on info.

Do they have two piece welded versions?

I don't see a list of diameters, widths, and backspaces?
