I don't believe you mentioned if the pines are fully mature. If they are, it could be tough stand hunting for a bow hunter. Stalking could sure be an option since the pines stands are usually pertty quiet. Like you said, pinch points, and gully crossings are good places to start. Also if you could find an area of blowdowns, it maybe good. If there are a lot of blowdowns, you could also create some funnels.
