I expect their twist locks are better than most, but you may notice the more expensive Lekis have external clamps
I haven't any trouble with the clamps getting caught, just the baskets on the end. They ripped off eventually, but they aren't so good in snow after that.
Used to have some twist lock macpac poles but they used to loosen themselves off sporadically (worst in tussock) and then let you down (literally) when you went to lean on them on something steep.
