Just out of curiousity, is the 8001's power that much greater then the 7001 that it is worth the extra weight and money? We personally have never used an 8001 yet, but have been told that there isn't that much of a noticeable difference. If you were dealing with thick or wet leaves maybe, but the added weight and price didn't make it worth it. What do you folks think? I have seen quite a few threads where people are talking them up.
