Ok, wouldn't be the first time I missed something new on the market. I haven't been in a saw shop in a couple months, and I like it that way.
Just applying some sawtroll specs/info to the situation. They call me a troll also because we live "under the Mackinac bridge" in the lower peninsula.
Nice video also, though that thing was ripping pretty hard for a 555 lol. Seems to have a lot of grunt (torque).
The 555 was ok but for 5cc more the Echo hauls the mail. I don't feel much "in the hand" weight and has a way better powerband (kinda the point of my consistent liking of Echo for the $)... also the Echo does great with a 27" bar, the performance drop on the 562XP was notable going from 20" to 24" so I couldn't see it getting beeter with a 27'28" bar. Again, all just my person thoughts/observations etc.
