I fly a fast pointy thing for a living, am involved in a Cherokee group and was offered a flight in a weightshift microlight by a friend of a friend.
Without doubt it was some of the best fun that you can have in the air. It's a bit like a flying motorcycle. If a Cherokee is a Ford Mondeo, then a flexwing microlight is a sporty motorcycle.
The only drawback for me is that you can't hire a microlight so you have to buy one (or a share in one) and I can't really afford any more toys
