Si - not a JAA rating, UK only and useful only in UK FIRs.
Evo - once you have it, you will want to use it. It's not designed to fly you from major airport to major airport under IFR. What it allows you is a bit more scope. Having it as an insurance policy is useless if you don't practice. Having to fly an instrument approach for real down to minima 24 months since the last one is going to end in tears.
