There is a new category of European Light Aircraft – 1 (ELA-1) for short. This is to be based on CS-VLA / US LSA rules and will allow many of the advantages of the micro with 4 seats and low running costs.
As has been said the touring side is not a problem, and the IMC/Night is not too much of an issue unless you have an IR which less than 1% of European pilots have.
I fly a home built VLA (based in Staffordshire) and enjoy most of the advantages of a micro but with more useful load, speed and equipment (CS prop etc).
