Based on the enormous amount of fun I had as a CCF cadet 30 or so years ago, I'd say if you can afford it, go for it - they're flippin' brilliant things.
If only I'd realised at the time how lucky I was, being hung upside down by my harness doing loops, stall turns and all sorts of other silliness rather than doing double maths I'd have done even more of it than I did!
