When I talked with Peter about the tripple, he said it was MORE streetable than the DD. There is a guy running around here with a 900+ hp Dirtymax that has a tripple and he back up that statement!
Has something to do with there being 3 disk's and they slip just a bit on take off and doesnt have that big single, DD jerk. Its still a 4200# plate load, so with upgraded Hydro it has the same pedal feel and a light DD.
