Cuinrearview,
Wow, I don't think ambient temps have much to do with how smart a person is. That's quite rude and petty.
Life doesn't stop when the temps drop. I still make money runnin saws all winter, and occasionally have fun learning saws new and old. Why not compare saws? They used the same bar and chain.
10 below is t-shirt weather. In this region of Alaska, these minor below zero temps start in November.
Leeman,
There you go with some typical assumptions. My 2172 is no different than the most recent husq 372. Again, the cut speed was acceptable for any cutting I might do. If it wasn't, I port all my own saws to run how I want them to run.
For guys that actually use saws for a livin, nobody cuts with dry powerheads. So about that weight: Full of fuel/oil the 2172 was actually a few ounces heavier, same bar/chain. May be the heated carb/handle stuff.
I couldn't notice the weight difference when I'm wearing a bunch of winter clothing, chaps, loggerstape, wedges, helmet, medical pouch, etc.
Have a good day folks, I gotta go finish a cut job while the winds are calm and im blessed with single digit positive temps. 30-40 birch trees.
