Dave, they all have T-bars don't they?
Or do you mean Corally's upper pod?
As I see it, first choice cheap or expensive.
If you go for the expensive side, Second choice, whatr are the main differences between the RoadKill and the Corally?
How about parts supply?
Will you be racing carpet or outside?
Bumpy or flat?
Why do you esp. want the tubes?
Well I've got a Coraly M with dampers on order as is.
So my choice has been made.
When I raced it I'll keep you posted.
Good luck.
