>>9146996From my experience two-cycled (like a weedeater) are the most poweful. That is what I used when I worked for metro parks, and commercial landscaping. But recently, since I don't need to use one all day, I have become a fan of the small DeWalt battery-operated blower. Especially since I have a DeWalt tool kit, and can use the batteries in all of the different tools.
