We absolutely hated the Echo 9010's. Just gangly things. Utterly horrible triggers and throttle and way to long/high up from the tube barrel. Super awkward activating the thumb idle/cruise control lever. Mega resistence from the tube and elbow all the time too. Always were fighting the thing.
Never seen a backpack blower suck so much debris into the fins/fan module behind our backs. Not really that comfortable on the back as many state here, in our opinion. The front chest straps leave alot to be desired.
We tried the Stih BR800's too. We thought those to be more comfortable. Really like the adjustable length bottom section of the tubes. But I've also seen and heard tons of complaints over time about the mechanisms.
Don't get me wrong. Both the Echo and Stihl big boys have a lot of power and airflow.
In the end, the Husqvarna 580BTS and the new 580BTS MarkII's just fit the overall bill a lot better in our opinion.

Yes I double fisted Husqvarna 125b handhelds sometimes in my first season. If you side discharge in our northern grasses, whether or not you have an OCDC(operator controlled discharge chute) you're going to have grass on hard surfaces. It is pretty easy to flip the lever, pull the starter and sling the 580bts's over one shoulder or two,2,to,too,tu shoulders and hit the accounts when blowing off. It isn't as rough on you as you may think. It does save time with the speed and power of the backpack. We edge all hard surfaces every week here as well. The handhelds whether gas or battery just are too slow to efficiently blow off everything and all the edges cleanly in a timely manor.
For what it's worth, as you grow you will want and need a backpack blower. It is just a matter of when you get around to purchasing one. And no you most definitely will not be going with a battery backpack blower in the near future. Until the batteries can have at least 4 times the power output per watt/hour and longevity per charge, there is no way a manufacturer can engineer a backpack blower to do what the gas can do today.
