I used to carry a staff and then abandoned it in favor of trekking ples for a variety of reasons. One was weight. My staffs were quite heavy. Another was uniformity. I would be hard pressed to find two staffs that were roughly the same configuration and so it would more of a problem for me to use them in pairs. I did meet a guy on the AT many years ago who went by "two sticks" He did use two different staffs as a pair but I was not able to really do so. I have to use sticks in pairs because of my dependence on them for support and balance.
