Sign me up on the list with Ole Sag and Black Frog for the 3track cams for my Supernova.
I have yet to see a better designed system.
I hunted with X-cams this year -- a Martin Slayr with a sub 7" brace. Never had a clearance problem with the cables, can load arrows just as fast as any other bow I shoot, and my broadheads flew awesome right down the middle out to 60 yards (furthest pin I had, but I am sure they would have kept straight out farther). If you have clearance problems on a bow with a more generous brace, I would put money on either your draw length is too long or you have a poor grip.
I am still rubbing the lamp
