Andy,
sorry I missed this thread before. I can only add that I am sad that I only got to dive with you a couple of times and how sorry I am that you have to give up.
Whenever you get a free weekend day, or a Wednesday evening, let me know and if you fancy giving it a go, you can come up in my glider. It's a bit like diving:- summer sport - check
- blown out regularly - check
- loads of very expensive kit - check
- highly complex computers with only 2 buttons - check
- spend all day for 1 or 2 hours of fun - check
- have to talk bolox in the bar afterwards - check
and finally- a rapid approach to the surface can really f*ck up your whole day - check

Cheers, Chris
