Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

Anyone know what the system weight is on P2Max w/ S-Works cranks versus my current setup of Powertap with S-Works cranks?

For S-type they claim an extra 122g for a 130 bcd. So if you go from PT G3 at 325, to a DA 9000 at 247g. You're adding 44g.
