ok, i know that before gaving out advise you want to know all the details so here goes

- i am 187lbs
- i use campag vento wheels for training, racing and tt
- roads around here are not smooth, tend to be bumpy and potholes ( although i try not to ride over the potholes )
- i use ultralight tubes and pro race 3 tyres

so my question, i was hoping to keep the ventos's as my training wheel and upgrade to something lighter with better rolling for racing and TT's

ideally budget between £250 and £350 so probably going to look on the forums or ebay for good used wheels

not knowing so much about wheels or what i should be looking to use in races, the first ones that come to my attention are campag zonda's and mavic krysium's

which would be best or what are the other alternatives that normally sell used within my budget ???
