Pines are money trees, and don't provide any forage for the deer. Also, If you tried to hinge cut a pine, I believe it would break off and you wouldn't have achieved anything. The trees you want to hinge cut are trash trees that put on a lot of foliage that deer will munch on and bed in. The idea is to cut the tree so that it doesn't die, but continues to produce, thus the term "hinge".
