The commercial guiding might seem uniform and boring, but in reality the mass commercial guiding is for a time. A very good opportunity to test and learn a whole set of different skills. Both hard and soft, as for managing people. And to recognize the opportunities the terrain gives you. As well as where it will restrict you.
This is something you wont have time to explore if you do longer trips, or if you don't guide as much. But being on the ice two times a day. In the approximate same area, you can really get a feel of what is really good. And how different guests act in different places.
