Austro
Hi 4535Jacks,
Similar position to you but a couple of months ahead - I've taken Austro for MOD1 on the assurance that the UKCAA can use them to issue an EASA license if a deal is made or a UK license if it isn't - either way you've covered if you get you license in the next 2 years to fly either in the UK or the EU depending on where your CPL/IR get issued. The other upsides are cheaper (£45 per exam) and the results are instantly available which can be a relief - some of the guys managed to get retakes in the same sitting though I believe Austro have said you cant do that as of end of Feb...
Side note, assume you are using BGS? My plan is similar to yours in that I don't really want to fly outside of the UK, but would rather instruct - especially Aeros/UPRT- interest to know where you're thinking of flying?
