Mate! As a UK jumper as well I understand - I bought an AAD (an ASTRA) after reading the CYPRES saves statistics - whether you FF or RW they've got to be a good idea, just ask anyone who've they have saved. I used to jump without an AAD until reading that statistics page - hopefully I'll never need it but, like any insurance, you can't rely on it but it's a little gadget that could save the day, and your neck - literally. £660.00 well spent!
