Chicom, if you weren't planning on it already, can you comment on proper use/techniques (when you have time)?

I imagine it's a whole different ballgame to spend 5 hours a day doing it versus when I go out in the backyard to deal with a fallen treelimb.

You've also hit on something very critical here: we only have so many hours and so much energy. We have to chose how we expend them wisely and use tools that can maximize the results of the labor.
