I'm back from a fish taco eating and beer drinking marathon in Mexico.  I did manage to cut the first finger nail on the 38.1 mm down tube, but that's about all.  The tube weighs 292 gms., not the advertized 304 gms. That's a fair amount for an S3 tube.  I also recieved the drop outs from Paragon while I was away.  They weighed in at 94 gms. a pair.
