It seems blowers are always being tested and compared against one another. Prior to today I had a shindaiwa eb630, redmax 8000 and a giant vac 8hp push blower (about 10 years old). Today I added the new Force Blower 9hp to the blower family. This blower seems to have a lot of power to it. I filled a recycling bin with 60lbs of weights and it slid it across the floor. I can't wait to get it out in the field and do more more testing. Let me know what questions you have and what tests you'd like me to try.
