I know three people who have had Europa's. One a consumate tailwheel pilot and LAA coach - spends a lot of time with other Europa pilots. One a professional pilot - whose aircraft has had a couple of 'off road' excursions and 2 props as a result. and finally one who had enough of being scared and converted it into a trike.
So that pretty much covers the whole spectrum. Lovely in the air, with only 80 hp a snail getting off the ground, and even after all the mods a little unpredicatable returning to the ground unless it has conventional gear, would be a simplistic summary.
The only other issue would be the number of compulsory modifications it seems to pick up.
