I daresay you got that right, sir; but I am not going to take off at more than 12 kts cross in my Apollo Fox, not until I've grown a good deal more of belly and/or pilotship! The point is "who was the demonstrator" , I reckon.
@Rod1: yes, wing loading must be the ultimate deciding factor, but I am not qualified to judge there, as yet.
