60cc my favorite is 20in 3/8 full comp. Easier to maintain the cutters then .325 although in smaller wood I am certain. 325 is a bit smoother. A 40 to 50 cc saw with 16inch. 325 is a nice set up for cutting a lot of small stuff but when you get 36 vs 40 cutters on 20in the faster sharpening times seem more beneficial. I don't always use it but prefer skip in longer bars to reduce sharpening time, and I hardly think it cuts slower buried in bar length wood. As far as dulling faster , my experience seems to indicate dulling is due much more to wood condition and circumstantial conditions vs.number of cutters. Extra cutters I don't even notice extended time between sharpening but especially if you run into something that dulls you bad you spend a lot more time filing more cutters with full comp.
Talking about sprocket size biggest thing I notice is fuel economy -runtime between tanks. If my saw has ample power for the bigger sprockets I prefer them over the smaller sprocket which usually seems to have me putting fuel in the saw more often. 60cc I use 7t 3/8 with 20in bar , a bigger saw with a 20 or 24inch I usually prefer 8t. Small saws using .325 16Inch I like 8t as long as the saw has ample power with it.
