Anyone have the newest redmax backpack blower? The one that has a 79cc engine( I think thats right, either 79cc or 71cc??) I looked at it online and Im going to buy it once my stihl dies. I assume this is the biggest backpack available, Does anyone know of one with a bigger engine than the redamx? I love my redmax trimmers and I assume their blowers are just as good. Pros and cons of this blower would be appreciated. Thanks guys.
