Lenny, all I can tell you is they are bloody light, so I'm not suprised. I wieghed them once to find out how much lighter a ProClass was, and it was a decent amount, like 10% I think, maybe more.
Sorry about the vagueness, but I've slept a lot since then.
Also, you mid-schools will be 48-spoke won't they, ie loads heavier.
Spen
ps - you coming to Blackpool again tomorrow
