Georg,
Are you considering to run a CS1,CS2 type Lenco or are you referring to the 1200 Street model ?

Think it would make a big difference on clutch selection, although cost will be similar, something like a Bonafante will be around $3500. But will need maintenance/checking, but less so on a mainly street application. Then again, what sort of HP you looking to put through it.

A bruno type Lenco, with a converter, as mentioned earlier is another option to consider
