Which cranks for my Vivalo?

Dura-Ace or Sugino 75's.. I ripped all my hair out and got Dura-Ace FC-7600.. cost me a fortune, but I'm happy with them ;)

Oh, but check the BB! if it's a Dura-Ace I'm not sure it will have the right chainline with a Sugino crank. and visa versa.

They should be the same (both use a 109mm ISO spindle), but I've got a 43.5mm chainline. It has been decided that I've probably got a JIS taper spindle (i.e. for Suntour) at the moment though, which is what is causing the trouble.
