A lot depends on budget. 7vrn are chinese carbon which are supposed to be good badged up by Brooks Cycles you can buy the same frame for less but then you don't get the warranty.
Most Dolans are good TC1 which replaced Track Champ (and resolved the seat clamp cracking issue)
DF3 's are great DF4 are prob the best track frame for the money then you start getting into the rarified atmosphere of LOOK , BT , Koga but the DF4 will hold its own against any of these.
maybe ideal was the wrong word..
happy to be recommended/offered others!
