Lakeside, check my sig... I have some time behind my MS290. It DOES get heavy after a while, especially when using it for small-limb clean-up or overhead cuts. I, for one, was not bench-racing; just commenting on the subject at hand BASED ON MY ACTUAL experiences. In hardwood, trudging through snow, cutting overhead, pulling my 18" bar (.325 RS shop-fresh chain) through 28"+ locust and oak, the saw did get heavy, did bog, and is fast becoming my mid-range machine. I'm not looking to lay down $800+ of beer money on a 460 for sh!ts and grins - I found the upper limits of where I'm comfortable running the 290.
Did I slam the saw? No, I actually like mine for what I use it for, I just think it's a bit much for the stated career path.
Based on my experience, it's NOT a "face cord a year and light clean-up" saw, and I stated just that.
Sorry to step on you "pro-toes" I was just answering what was asked. Dayam.
