We would dive air to 60m on OC mainly due to the cost. All of our local weekend diving is in the region of 45m-60m so you'd be going through the He quickly on OC.

We wish to avoid/reduce narcosis as much as possible diving Rebreather so can't compare the effects of narcosis between OC and RB

Since switching to Rebreather we dive a mix on every dive. He cost is insignificant when adding He to your 3L dil and you get several dives from a full dil. We feel a clear head is important to sort out even a small problem and be able to monitor PO2 on a regular basis. I'd say anything past 30m on a RB, for the almost non existent effort to mix up yourself and very low cost, why not use a He mix.

Just our opinion however, others do things differently.
