Well what a debate...fantastic! I'm sorry cusco I cannot offer any advice on the civilian market Zoot Suits, exept to say that any is better than than none at all. We have a suit wich is issued to all three services as standard. (bar a few minor differences). And as for the comment about parachutes from Beagle....your still gonna get wet at the end of the ride down.
I have done no research on this but..I'm sure an IM suit and a good quality strobe light would be cheaper than a dinghy. I know which I would fork out for, and it dosent bigin with 'D'!!
Hope all your flying is enjoyable whatever and wherever you go.
