if your using nitrox to 50% then you'll be fine with your regs as they are.

This would be true is the reg is brand new yes, but if the reg has been taken to a dive centre for a service how can you tell if a o2 safe grease was used ? Truth is you can't.
The commonly used o2 grease (christolube) is maybe 10 times the price of silicone grease so chances are silicone may well have been used unless a o2 service was asked for.
So if the reg is new and not been in for a service then yes it should be ok with 50%, if its been serviced then no it may not be, it could be ok but is it worth the chance? There is no AA or RAC at 25m
