hi - quick (possibly stupid) question ... I have a track (bought cheap) which looks decent but which has all of the track guides gone except for maybe 1/2 dozen (i.e. hy-fax running on the rubber of the track). Today was the first time I gave it a good fast long run and I noticed a very pronounced burning rubber smell. It also seemed that when I stopped (to check the source of the smell) that the hyfax was 'sticking' to the track rubber. (Hyfax is brand new). Seems to me that without those clips the track (or the hyfax?) is going to wear out very very quickly. Can a track last for long without the clips/track guides?
