in a practice race last week my hot stick slipped, i twisted it to tighten and it rotated 'past the cam' and slid out a lot more, all this while i was trying to bear away behind a laser. crunch! it was ugly. ok it was an old stick, i have broken two others. i move around on the tramp a lot and often put my weight on the stick. now i'm using a bamboo pole- i know it wont slip! the question is, what are some reliable alternatives to the hotstick?
