Is there some kind of break-in period on the 770? Did a bunch of research on this new model and finally pulled the trigger and went out and bought one. Tried it out on the lawn(NC, heavy leaf season right now) and can't say that it is as phenomenal as all of the reviews. I am currently running a Redmax7001 that is about three years old and the Echo doesn't seem to have the extra power that it boasts. Not to say that I am disappointed in the power, but for the extra $70 over the Redmax, I was expecting a little more.
