Watched a big maple start to sit back early on a standard cut last season, heart absolutely dropped. Switched to a bore cut on the next one like it, and the difference was night and day. That hinge stayed open, gave me all the time I needed to get my wedges in and tapped without any panic. The guys who call it slow have never felt a kerf pinch shut two inches into their back cut. For heavy leaners, it's just the right way to work.
Argue that slow is better than dead. If a heavy leaner has weird pressure, a standard face cut can close up before your back cut is done, and then you're dancing. The bore cut lets you leave a solid hinge and set wedges while the tree's still supported. Yeah it takes an extra minute, but that's time spent reading the wood fiber instead of guessing. What's their wedge setup like on a standard cut for those leaners anyway?
Man, you nailed it with the "dancing" part. I had a hemlock start pinching my bar so fast I barely got the wedges in, switched to a bore cut and it was like the tree finally decided to cooperate with me instead of fight back. I keep a couple of those big plastic wedges handy too, they're worth their weight gold for that awkward side pressure you don't see coming from a leaner.
