I have a very small yard (2500 sq feet) but my neighbors and I have a lot of trees with a tremendous amount of leaves and acorns. I have so many acorns that I can fill any where between 6-8 32 gallon bags. Can I get away with very good hand held blower (Redmax, Stihl, Echo, etc.) or should I spend a little more for a decent backpack: Husqvarna 145BT Echo PB413 Stihl BR340 Redmax EB4401 If the backpacks can't handle the acorns then I'll just go with the handheld. Do you prefer the throttle switch on the hip or on the tube? Why? Thanks!!!
