I've taken my telescoping poles (BD carbon corks) on two trips w/in the past year and a half. I was under the impression they were allowed.
I had mine fully collapsed, and on the side of my pack. If I angled them a bit, they and my pack were just w/in legal carry on limit.
For the second trip I put bubble wrap on the tips, covered with toddler socks to make sure I didn't poke myself or anyone else in the eye.
On some of the earlier flights I removed them from the bag, cause I though I needed to in order to close the overhead bin (I didn't). I specifically asked the flight attendant to help me remember not to leave my poles on board!
If they collapse I doubt it will be a problem. Helps if you can secure them in some fashion to one of your two official carry-on items.
Good luck!
