Hi all, anybody have any thoughts on the use of R427A (FX100) as a viable long term replacement for R22 in lieu of R410A which has very high operating pressures, the US seems to be going the way of 410A but Europe still not committed.

I realise that mainly the smaller units up to 15kW are using 410A but what about light commercial equipment say up to 50kW is that going 410A as well.
