I fired up the 445 this morning. Ran about a tank full of fuel through it. It meets expectations. I was noodling a number of rounds that were crotchy. Is that a word? It is now. I kept checking the new chain, to make sure there wasn't any slop. There wasn't. I performed about a dozen stop/starts. Each restart was 1 or 2 pulls. I think it's a keeper.
Yup - I saw the suggestion. I wanted a saw that my existing chains would fit. I didn't want to have to separate chains for my main saw, and my backup.
