@KayPam really interesting suggestion. I've always been interested in aerobatics and tailwheel and considering I have to get my night rating anyway I might just do it too.
The problem is that since my license was issued I've done 2-3 hours of flying, and that was summer 2015. So my SEP rating would be expiring this summer. This was due to moving country and studying/working all the time. If I didn't have the flying bug I don't think I'd have the energy/motivation for studying full time as well as nearly full time work!
Considering this, would you say that it is worth getting back to exam standard now again or just save my money until I can give my 100% to flying full time (in a few years)?
