Parachute always
I have taken to wearing my parachute (a lightweight National backpack) all the time (OK, not in the bath). It's not just the wings falling off that I'm thinking of, but also midairs (glider pilots in glider vs glider collisions often bail-out successfully). Given that aerobatic aircraft would be easier to jump out of than most tourers, it seems to me a good idea to wear a chute whilst flying, although if the engine failed I'd still try to land the thing. Could be a lot of clobber if also life-jacketed whilst crossing water.
PS: Evo: tomorrow, I'm bringing a spare for you, but it's a 200 year old seat parachute that makes you walk like a spavined baboon.
