Just wanted to say thanks for all your advice and knowledge. I was out for the first time with my new Dolmar 5100S (and related PPE) based on your recommendations here. I was doing Timber Stand Improvement (basically girdling trees, cutting a ring around the trunk), so it was almost too easy. The saw really wanted to fell them instead! I did safely fell a few small 8"-10" trees. I can see why this can get addictive, and this will probably be the first saw of several . Thanks!
