Keep in mind, I also mill. The 24" and 36" see lots of use when I do, and milling can dull a chain fast, you it is nice to have some extras. In fact, if you have 2 90 cc saws with 24" bars, you can let one cool down while you use the other. Milling is tough on everything. I try to bring saws to match the job. Several times, my 261 w/18" B&C can do everything, but other times larger stuff is better.
I knew milling generates a lot of heat and you need a ripping angled/math chain and it's strenuous on the powerhead.
Kind of like prairie dog hunting. Bring a bunch of rifles and rotate through them when a barrel gets too warm.
