i have both a NC29 trackbike and a MC21R i have ridden them both around cadwell park and i would say that i would lap slightly faster on my 21 with wire splice and endcans than on my maxton kitted 29 with endcan, like Fontyyy says between us we have had pretty much everything and really there is only the rider in it.
StephenRC45 can probably comment on MC18 Vs NC29 (in the wet), again it only comes own to the rider. LOL
