And another thing!
I too feel that microlights and the smaller LAA permit types are the most fun to be had flying. The extreme expense of hiring a PA28/Cessna in the South of England means that I can only think of the money and not the fun when doing so.
You can go just as fast in a microlight as you can in a spamcan, so unless you need to take more than one passenger or feel the need to fly on instruments then going beyond an NPPL M then A is not worth the bother.
