I wouldn't completely discount the Rush btw especially if you get a good deal on one. Its Reynolds 631 and the frame is quite light (4lbs - not bad considering its steel). The geometry is track worthy with good tight angles. About the only realy downsides are that the matching fork is not the greatest and its a little overpriced if bought new IMHO.

Nevertheless I push mine around a track a few times a year and it works pretty good for me but I haven't been racing long. At some point I'll probably upgrade to a dedicated ride but its working for now.

Handles street riding with ease though.
