I don't have much experience with square ground. I've bought some chain that come from the factory square by chance and it ran pretty good. i don't log any more but run a full time tree service with a dozen saws, about half ported. Usually end up running semi chisel because over the years I've found that properly tuned rakers (thanks BobL) run real close to full chisel in speed but cut 2-3x the wood between sharpenings and get almost twice as many sharpenings per chain. That's a lot more productivity.
The square I've ran is good for sure, but not brilliant. Everyone says square out of the box isn't that great and I'd believe it. I give semi chisel 2 licks per tooth with a round file and 5 strokes with a clean sharp file on rakers to wake it up and the difference is night and day. I hear guys make statements like "it's worth selling a saw to buy a square grinder ". I'm thinking boing of changing at least 3 or 4 saws over to square for use in the tree when climbing since it's clean cutting and time is critical to get ahead of cuts in some situations.
So how many are cutting with square? How's it working out for you?
