The new steel models are pretty badass in build

As far as the alluminum models go I've owned the 735tr. It was so so ,not to heavy,welds were pretty clean but was a little loud since it has fat tubes. It wasn't stiff enough for me as I could feel a little flex in the chainstay when I was in a out of saddle sprint.

If I were to go leader again I'd def get a steel frame from them. My new alluminum ride a 2009 FTP is pretty much all I need for track
