Blaze,
If you are still following this thread...
Try visiting your local Gliding club. Ask about a trial lesson or two. Ask if there is any chance of arranging an aerotow so you can experience some mild aerobatics. With luck they should be able to show you a few loops and/or a spin or two. Hint: Do your straps up as tight as you can and it doesn't feel as bad :-) If you want to do something different this summer holiday why not book a weeks gliding course?
PS: For insurance purposes most Gliding clubs can't give you a "pleasure flight" only a "Trial lesson".
PPS: Don't blame me if you get addicted!
