I cant imagine hiking poles or any thin aluminum tubing working - I am 225 and the stresses on those poles are really something. Are we talking 1" aluminum tubes?
Alamosa I was thinking that this would allow a pitch on the pole at an angle of choosing and less chance of slipping.
There was an Old Man with a owl,
Who continued to bother and howl;
He sat on a rail, And imbibed bitter ale,
Which refreshed that Old Man and his owl
