How you work that block of pine will determine how you can avoid those hangups.
Looks like you're on level ground so it'd be easy to judge your trees natural lean. All your trees in your block will lean "on the average" in one dominate direction.
Up here our spruce and pine has a dominate south easterly lean. So when I want to start felling, I start in the south east corner of the timber stand hopefully into a clearing or cut over. You may have to open up a clearing to work your "face" so you can work as a skid trail. As you work your block the "face" is moving Northward.
Here let me draw a picture. A picture says a 1000 words Lol.
