Mighty nice piece of work!
New member here, though I've been prowling around here and reading for a number of years. I've always admired the talent, knowledge, and artistry on display here and figured it was way past time to join up.
Anyhow, I thought you folks might like to see a much cruder attempt at a measure from forty years ago. It ain't much, but stood up to several thousand miles of tough Rocky Mountain trails back in my youth.
