Do what you do best and enjoy most. Find your niche and stick to it, and you’ll do great. We are a small company, but not that small. We specialize in large trees and limited access trees, essentially the ones nobody else wants to touch, and I enjoy playing circus director myself, I probably only run a saw once a month and get off the ground twice a year, and plan to keep it that way.
There are a fair number on here running lifts or buckets, some who only run lift/bucket, and there are just as many or more who only ever climb. It all comes down to what you want to do and how you want to do it. A lift/bucket can be a game changer, as it’s safer and much faster for some projects, but there are other projects that can only be completed by a climber.
