IMHO one of the reasons to go custom is to be able to talk directly with the frame builder himself. That way they can design for all of the idiosyncracies that you may desire in a frame. Why not go with a local frame builder who actually builds their own track frames, rather than farms it out elsewhere? I am not trying to dis Ebisu, as they do have some very droolable stuff there, rather just putting in a word for local frame builders here in the bay area or in the USA for that matter. Unless of course you need to have equipment that is NJS certified so that you can do Keirn racing...or just be the shiznit.
