Any time mine bend i go into the lodge and run the bent part under hot water for a few minutes and it bends back pretty easily. Be careful though, if you feel it not wanting to go don't force it or it will snap.
just buy the cheapest poles you can fin, and when they bend, just bend them back in between two solid things, like the back of a chairlift or something. or the ski racks by the lodge. your poles will never be straight though
if anyone is interested in buying new poles that arent gonna break or bend, look into scott poles. i've been using my old race ones after cutting them down three seasons ago, and they havent bent yet. and ive taken some super hard falls on them
