Curious to know what you got. I have a 6100 and like it, just a little on the heavy side for a 60cc saw for me personally, I typically will grab a smaller(55oxp) or larger saw(365) depending on what I am cutting. I have not had a chance to run to run any of the Echo 60cc saws. I do like the inboard clutch on the 6100, that is my personal preference, makes bar/chain swaps a lot easier.
I do however use it if I am going to help someone do some cutting and dont know what we are getting into. I run a full wrap w/20" and have had a 24" on it and it pulls it quite well.
