Thanks, Bear B.Hind.
i'd have to carry mine in my hands all the time (never run with backpack, too late to try now). i know they could be very useful on the climb out of the forest,. and after the 3rd CP, on the steps, and on those long slow uphill bits, but i'm worried that if i have them i'd walk even more than i usually do. on the other hand,if they made it easier, i might have more energy for the 7 bitches. In all that mud, it might give me something to hang on to, though!
