@ Magbarn, Isn't that echo warmup thing weird. They do work and then suddenly the sound changes and they run a tad better. I've never any equipment do that before. Like I said I don't wait the three minutes. It just seems weird waiting more than 20 seconds or so to me. Wasn't sure if there was a reason for it on the newer machines.
Still deciding between the Echo Pass And Stihl Kombi system. I really need to pick them up side by side see which feels better/lighter etc. That might be the deciding factor as much as anything. Although the Echo 5 year warranty is attractive.
