Checked out the Brazos site - fascinating - but their stuff is rather expensive. I have been using a walking stick of one sort or another when backpacking, etc. for years. I have used everything from a replacement shovel handle (cheap) to collapsible aluminum poles (convenient and versatile) to slightly modified poles found in trail side brush piles (ultimate in cheap). They all worked well.

I am inclined to remove the springs from my aluminum poles, however. Just useless weight and quite unnecessary.
