The Ax is a great little aeroplane for pottering around in, even touring if you're not in a hurry. However, getting in and out of them is an art form. I'd hate to try clambering out after an unscheduled 'arrival' on terra firma if the frame were bent. In comparison, the Rans S6 has an extremely robust steel cockpit cage and I can vouch for it, having suffered an 'arrival' in one. Spares for the Rans are no problem either.
