....... This was producing 4 to 5 cords per day.......Climbing over limbs and such, a couple more pounds at the end of the day could get dangerous. There is the added weight of the 372 also as a result of more fuel capacity that after 5 or 6 hours of cutting may be an issue. The poster did not tell us much other that the wood production so not knowing many variables , made me suggest the 357 which would handle what he is doing quite nicely. As I stated, people get used to saw weights but I did not know many critical things hence my overall suggestion.
I could not produce 4-5 cords of wood per day processing a whole tree or by just cutting from a pile already stacked in 20-30' lengths; that is if you are talking about wood ready to be burned. By the time one or two people cut, carry, split, and stack wood that is being cut in a day's time, 4-5 cords is a real stretch unless of course you also own a wood processor set up with conveyor etc. Now if you're only talking about cutting up rounds to make 4-5 cords in a day, I agree it's possible, but to get what I consider "firewood" cords, I would have to sit back & watch
As far as for throwing in the limbing & processing: from cutting the tree down, limbing, rounding, splitting, moving & stacking, 4-5 cords........

I do know for the limbing I would have recommended the 346xp, not the 372xp, but for production, for me anyway, it's the 372xp.
Some of the guys that cut with me are 65yrs old and all they say when using the 372 is that it is a pleasure to cut with; not full time cutters, just trying to stay warm and help each other out.
As I said, there's nothing wrong with the 357 (or the 262 and the 257 you mention, both close to the same hp family with the 357; 262 a bit more, 257 a bit less), I have one of those too. If I were to have to use only two saws it would most definately be the 372xp & the 346xp for saws of today. For quick cutting of firewood though give me the 372 any day!
Oh, and a few things to make gathering a bit easier:
