165mm on my fixed gear with 650c wheels, my cross bike (to avoid toe overlap), and my TT bike (for more saddle-bar drop and to keep my knees lower on the upstroke -- may even go with shorter cranks someday).
170mm on my road racing and long ride bikes. Haven't really noticed any difference between longer and shorter cranks to be honest (except in the reasons I gave above), power is the same. I notice more difference between 650c and 700c wheels actually.
