PMJ/Polar the clutches are total different, at first when I had the single fitted it felt very snappy compared to the twin but after 1/2 an hours driving it was like it had been there for ever!
I use my car for road and track day use only, so apart from the race off the lights (where it is fine)I have really no need to spend the extra on a twin/triple.
Spaek to Abbey they game me the option which I am very happy with. Just depends on if your going to drag the car.
