Clutch for a 500

[EddyP]

Evening all,

I need to get a clutch for my 500, there seems to only be two options now, the Helix from TVR parts or the Billet from Dom.
The helix is quite a lot cheaper understandably. Have any of you fitted a helix? how did it compare to the original AP?
I'm planning to fit the larger bore slave at the same time so it might keep the pedal weight fairly similar.
