So why the 270 and not the 290? There is a pro saw in there, maybe the 260?, but the prices all seem to come together in the 200 series non-pro saws and I can't see why you would want less power. The 290 might weigh a bit more? Just curious. Oh, and I have never worn chaps except when packing horses. Nobody wears them here. Maybe its an east coast thing. We wear ear protection and I will wear eye protection but no gloves or chaps. The large forest companies might be forced to do it but they also wear corks.
