For the average, a couple cord a year, no you don't need it. If you want it sure. I don't need 30 saws, most over 90CC's, but I want them. The sharp chain is the one thing the average fire wood guy does not understand. Almost every friend I have that has one saw for yard use, can not keep it sharp. You can look at the ground around where they have been cutting and see the little zip marks in the dirt where each cut broke through and touched. So, the extra speed you get in a ported saw is wasted on the average guy. One thing I know is that bigger chain dulls slower than smaller chain. I can take one of my 100CC saws with 404 chain on it and snip right through a nail or piece of barbed wire. If one of my 70-90CC saws with 3/8's hits the same size nail it will wipe out every tooth on the chain. 325 touches the ground a couple times and it's gone. One project that keeps getting put to the back of the bench is an old Stihl 08S that a friend pulled out of a dumpster and gave me. I think it's 55-56CC's with a 20 inch bar, pulling 404. I'd love to try it out for a few hours. Maybe I'll send that one down to Randy to work some magic on. If anyone takes offense because I say the average guy can't keep a saw sharp, don't. The fact that you are hear puts you above average, or you will be soon.
