How you are configured and what you are doing is the question. I have lately begun to think that my 7106 FEL is ill suited for my 1220 Ford. It puts too much mass, too high, to be safe on anything but flat ground. I've had it on two wheels so often now, that I'm a bit paranoid. I'm also realizing that my vision isn't what it once was. Sometimes I'll walk a section with and with out my glasses. With the glasses, everything looks good. But then walking without the glasses, I can see and feel that the terrain is much more steep than I thought.
