I went for a trial lesson at Long Mynd a year or two ago. Aerotow, and yes, you need lots of rudder to turn, but no big deal. It would all have been very peaceful, but the instructor made me do a loop! It was fun, but I started to feel ill, as I'd told him I would if we did aeros. Anyway, I enjoyed it, and very friendly people, but it's never grabbed me enough for me to take it up.
