Can anyone help me out on some information on Campy Khamsin Disc wheels?

A local guy to me is selling his in good condition, 4 years old, but no use in last 2 for around £100 with Tub and block.

Is this a good deal?? I cant find anything on them on the net - are they heavy? Aero??

I am a 17 year old Junior, race 2-3 drafting races a year - rest are olympic non drafting. I currently have an old set of Rolf Vector Pros on a giant tcr (road) - would this disc be a good buy???

thanks for any help
