Thanks Howard, I did some more digging on google after posting, turns out the cirtix wont work on 1s at all, however the HW just stock will, so thats fine.

I am looking at kits at the moment, i had a serpent s120 ltx v2 previously but didnt get on with it at all..looking at the yokomo r12c3, looks beautiful but it seems like you can only use their wheels with a very specific offset and only mobgums or yokomo (obviously) make pre glued n trued sets for it.

Its either that or a CRC carpet knife XTI but the yoke does look beautiful but the wheel situation does put me off some.. anyone wanna shed light on it?
