To revive this thread. We were out clearing trail this weekend which we do more than 750 hours per summer. I only mention this to give folks and idea, how much these tools get used. On this section, no one had touched in years and quite a mess, as seen in the photos. Its about 1.5 mile hike in just to get started, so we can not bring every tool in the shed with us. Weigh is a premium when you must hike in. This day we brought with us 2 power units, two string heads and one saw head plus other accessories for this type of work. The string heads hold pre-cut .155 strings. What's not seen is all the overhead branches cut with a pole saw. Hope that helps.
