I don't know of any 88/90 cc saws that are as light as an 044/440 or 372, so if you have to do some limbing with it, lighter is better.
The 60 & 70 cc class saws are likely the most useful for most stuff, with smaller saws being better for limbing & smaller wood, and larger saws for running the big bars & milling.
I'm getting a ported 066 from Randy, it will be used with the 36" bar and for milling, but I don't envision it getting as much run time as my 044/440 & 046/460 saws. Although I did cut up 2 nice large Red Oak during the past year that needed the 36" bar. The ported 460s pull it well, but it will balance better on an 066.
