Colony Venator Cranks vs Demolition Vice (input on either?)

Last piece of my new custom build will be cranks. Im after chrome, 160mm and live in NZ so im limited on what I have access to. Leaning towards the Colony Venator cranks as they're about 700gms for the set. The only thing is their shortest is 165mm and I was really wanting to get down to 160mm, but I could get away with the 165s. Demolition have the vice but they're around 950gms a set and they're not due into the store until later in the month. My bike is sitting around 11.4kg at the moment with some nasty 8 spline cranks on it temporarily, so im already quite light but I'm hoping to keep it that way or even lighter again. Has anyone ridden either/both and have any useful input on them? Cheers.
