Good move on the non-ethanol gas. I have a client that runs a lawnmower (Jacks Saw Shop) sales/service shop & he swears that damage from ethanol gas has been the biggest cause for repairs for the last 10 years. Fortunately it hasn't been as difficult as it was to find non-ethanol gas these days but you do pay a premium for it.
Also, I know that Lowes & Home Depot sell a non-ethanol gas & 2 cycle premix now. Again, its a premium but its well worth protecting it.
I'll be getting the Milwaukee pole saw, I'll let you know if has decent torque.
I bought the milwaukee m18 pole saw w/ a blower on special 2-3 months ago. It's great! I've used it to clean up some of the trails around the property we use to walk the dogs. I bought the 3' extension about a month later but haven't used it yet.
As far as I can tell, I have 5 different trees on the property. I don't plan on cutting the aspen or larch trees, Aspens sound amazing with a gentle breeze and both turn colors during the fall.
