I picked up a redmax 8001 today and tried it out at my house and it is stronger then the stihl 600's. It is alittle bigger then the stihl but when I compared them together it isn't that much bigger the air filter makes it look bigger. It felt just as comfortable as the stihl and I didn't really feel the weight to be a issue. My dad also played around with it and also liked it, the weight didn't bother him. It is more powerful then the stihl blowing leaves but for regular lawn cutting it is overkill. I here alot of people saying it's heavy but I didn't think it felt any heavier then any other brand once it's on your back, maybe if you weigh 120 pounds then maybe it could be an issue. Tomorrow will be the test at a couple cleanups if it goes well I'll picking up another one for cleanups.
