Ze,
Interesting point on reducing knee flexion angles.
Occasionally I find myself in a large boulder field. The boulders are irregular shapes, say 3 feet, 5 feet or more on any one side. I find myself hopping between boulders, which can be a high risk endeavor. You can fall between two large boulders or hyper-extend your knee when you land on the next boulder. Maybe I am too straight-legged when I perform this task?

Thanks to everyone for your thoughtful answers.

Scott
