I think you guys are being a little sensitive about this.
Lotek, I think your observation about the TPI and general quality of tubulars is on the mark. Whether its tubulars or clinchers, construction, materials, and build quality can make a huge difference. I think that's what people are generally feeling. A low grade tubular feels pretty much like your run of the mill clincher.
I rode some pretty low grade tubulars and some good ones, there was a noticable difference between the two.
by the way, I mis-spoke on the "tension" in a rim - meant to say compression.
