You're thinking way to much man.
I once was taking picture at a contest, so had a camera bag and shit so didn't take my poles with me. while practice, lunch and at the end of the contest I went lapping the park without my poles. It was strange at first but then I quickly realized that I could grab my skies with more ease then with my poles.
So I spent a few other days riding without poles and noticed that it was actually pretty fun. Plus it one less thing to take with me, and since I often take the train it is a little easier simple to get on and off. But if I know that I will be skiing out of the park I will take my poles. Ohhh and plus I look so much cooler shredding without my poles...
I now see that I am becoming an aerialist, guess that I will have to go back and shredding with poles.
