Eh, for the convenience vs. a couple lbs... it's worth it. there are times that I wish I had a rear wiper in my Sedan.. b/c the rear defroster doesn't work except 3 lines, and even they take forever.

I'm checking the legality of speedglas for rear windshields... if I can get it legally, I'll just get some defrost paint and put the lines back on it, or get a sheet of heat conductive plasma.. it's a clear sheet that has a heat-building material in it, that heats up almost instantly when hit with electricity.. I've only just heard of it, haven't done any research on it, and it's probably really expensive.
