Howdy! Thanks for also speaking a different language. I hope your problem sorts itself out.

6 and 7 are my favourite. I don't know which one I like more, because it depends on my mood at the time. I also quite like 10, despite certain problems, 4 and 9. I would love 8 but I hate the junction system. The only FFs I don't like are 12 and 13. Never played 11, though.
