Good question. Might want to ask in the gear forum. The only pair I have I don’t like, but they will fit in a suitcase. However, that’s moot since I don’t want to take them. (They’re an unknown branded pole I got in Chamonix)
For me the biggest issue is wobble or looseness when you shake it. For that the two sectioned LEKI might be a good choice. Recently I tried a pair of Black Diamond 3 section trekking poles in the store. Did not like the feel at all, vibrating, wobbly when shaken, which was a bummer.
A few years ago I thought getting a pair of 3 section ski poles would be great for travelling. I made it with them one day in resort and decided I couldn’t deal with them. The last thing I wanted on some guided day was a wobbly, distracting pole. Plus what if I had to lean on it in some couloir? Would it collapse? I rented solids instead for the remainder of my trip.
One time at Snowmass I leaned on a Goode pencil carbon pole so hard it was bent like a fishing pole. Wasn’t even my pole, and the guy who lent it was right near me. At the time it was the main thing keeping me from sliding down a 40 deg slope. I’d popped a ski and got tangled in an odd position. It was a weird situation, basically unhelpable if I let go. I expected the thing to snap at any moment. It didn’t, which was impressive. I broke my own Goode’s twice, but not by loading the shaft.
