I have recently got myself a sport set, I must say I'm chuffed to bits. The slot is deep and completely covered underneath, no more 'clacking' from un-trimmed ninco guides.
The grip does seem to have diminished, but I think that adds to the fun. The track is easy to fit together, and its flexibility in the joints allow you to just pull together the last peices that don't quite fit.
The only thing that is slightly dissapointing in my opinion is the racing crossovers, I tend to brake during the corner rather than before, and often end up stalling between the rubber bits where the lanes cross.
