or am I confused? Can I take a 53/39 crank + 13-26 cassette with small cage rear der and slap a 50 big ring and a 13-29 cassette on and expect it to not explode the rear der (if you haven't figured it out already, I am running Campy)?

The max tooth difference span is the same, i.e.(assumes use of cross-chain),

39 - 26 = 13
53 - 13 = 40

40 - 13 = 27 Teeth difference between min and max cage ex
