Adjustable Poles

I had a pair of the K2 party poles last season, I never used them in the park, just for groomer skiing and bc skiing. The adjust feature is a nice addition to a pole, but after about 20 days the mechanism stopped lock off the shaft properly, so it had a tendency to get longer/shorter which is annoying. Also they are more expensive than your standard pole, and considering how frequently poles get broken, you've got to question the point of getting a pair unless you really need them, ie. touring/hiking.

Loose the poles all together.  You just don't need them.  Skiing is better and safer without them!

I had a pair of black diamond adjustable poles and they worked great all last Season and the seasons before also I break poles a lot and the top part never breaks only the bottom and you can buy the bottom part for like $10 vs. A whole new set of poles. Then for the back country days or hiking you can extend them and they work great

I don't know about that... Maybe in the park you don't need them but if you use them right they can be pretty helpful and useful outside of the park.

This. I wouldn't be caught dead in the park with poles, however, I am rarely found out of the park without them. Being an ex-mogul skier, I value my poles and understand their importance when I'm just skiing the mountain and whatnot, yet cannot see their relevance in park skiing.

Anyways, when I am using them, I like poles that cost small amounts of money and I like to keep them at a fixed length. Less breakable and more cheaper that way.
