I always buy track cranks in 165mm as you can always sell them for "good price"- have a look on eBay, there is a significant discrepancy in price between the "everyone wants them" 165mm and the unfashionable 170mm ones.
As I've said before, I've gone round Herne Hill on my road bike, with 175mm cranks and been nowhere near grounding a pedal.
Of course, I have no experience of other tracks- but then my "track" bike is used to commute in London, so it's not that relevant really.
I do always buy 175mm cranks for my geared bikes, force of habit there really- plus the size of frame I buy is always specified with 175's
