I've heard that loggers have one plus a spare. Then again, clearing crews have to carry dozens and dozens because they run them WOT all the time and blow them up.
I log and I do carry two saws with me. For most of the summer it was a 562 xp and a 372 xtorq. My routine is to run a tank through each then take a break, rinse and repeat.
I am currently cutting much smaller stuff so in my truck is a 550 xp and 562 xp.
I also own a 2171 which I grab when I am blocking firewood.
