If you haven't ran either the 7500 or 8500, you should. They both outperform anything you've run of Redmax's up until now. Both of them will. I have the Husky 570 BTS and have owned it since it first came out in late '11. It is the same blower as the 7500, but has much better shoulder straps and a few other niceties. It is lighter than the 8500 and performance on real world debris is so close that there's nothing between them, yet the 570 is lighter and uses less fuel.
