I have been reading on lawnsite for several years, but this is my first post. I've been looking at buying a blower this fall. From all the reviews, I've decided to get the echo pb-770t, instead of the stihl br 600 magnum. I've been heavily researching the echo blower the past few weeks, and I'm pretty sure the specs for the blower were 765 cfm and 204 mph. If you go to echo's website now it says 756 cfm and 234 mph. Can anyone else confirm this, or is it just a mistake? Have they updated the blower and changed something small? I think a 9 cfm hit would be worth it to go from 204 mph to 234, wouldn't it?
