RS6, I will email you with additional comments/info, but it sounds as though you are on the right track in my mind.
I have owned the original version Tracker, Dave's newer style, the Aussie made EVO version as well as the TOPS release. I have handled thyour PRED and a couple of other makers variations through friends.
The ones that were closer to the original feel and handle the best due to their grinds and geometry. There is however, another variant of which 'would' be I think, the most popular and would possibly change a lot of peoples minds about them. There is not a lot of photos of it and it is one that Tom Brown had another not so well known maker construct.
