Is this because you own one and have never used a 600? I am curious as I love my husky trimmers, loved my husky blower also untill I tried both the 8000 and 600. I can tell you the 600 beat the 8000 hands down in all catigories. weight, power, comfort, and quietness. blew the same brick farther than the 8000. Now I have had 2 back plate failures with my 600 but I can tell you my service is great from my dealer and after the first one they started stocking back plates just in case.
