Thought I would update - I ended up going with SturubFlygklubb in Malmo. A really friendly bunch and the attached flying school was great to deal with. My main reasons were that hire costs in Sweden seem to be around 15% cheaper than Denmark, and I could get a Swedish license validation for free, whereas the Danish authorities change. So for the next year, Malmo it is!
2 questions which someone may be able to answer:
1) Would the requirements for a JAA conversion of my CPL be the same in all European countries? (as opposed to the 12 month validation requirements which each country manages separately). Or are the better/worse ones to do it in? (unsure yet if I'll do it, but if I end up staying for more than 12 months, I may have to!)
2) Any suggestions for scenic flights or places to visit on day trips in Southern Sweden / Zealand area?
