I think Track's intent was for the TourSic to be their version of the IQ Tour. I found the TourSic to be longer and slightly more angular downlane than the IQ Tour, which makes sense given the TourSic's higher RG. I also found it to be less forgiving of operator error. In any case, while I'm not sure that Track intended the Legion Solid to be their IQ Tour-type ball, it certainly seems to be filling that role.
