Personally i wouldn't bailout to air from trimix at 60m. You will possibly be breathing like a train and spiking the PP02 from 1.0 to 1.5 but more importantly spikeing the Pn2 from 2.9 to 5.53. This will result in a big wave of narcosis on the already stressed diver and could result in inner ear problems, nausea & dizziness.

2 X 40min 60m dives a day is pushing it as well. Run time will be 2 - 2 1/2 hours per dive. Decoing out on 02 would be advisable to clear the body fully but you would need to keep track of CNS. Too much drama for me Either do one dive or cut the bottom time.
