I am thinking micro chizzy of some kind probably carlton or oregon. I am going to use it mainly for stumping with the 3120 I have. I bought it used and it came with two bars a 32" and a 60" but the 60" was pretty beat up so I found the cannon. I am currently bidding on a massive silver maple removal that is around 7-8' DBH so things should get interesting if it pans out and if it does I'll get some pics and try and post them.
