Pasture Location. Flat or sloped

Hi, I am hoping that you guys out there in permie land can help me with a decision. I have 5 acres, about 3 acres in bush, 1/2 acre in marsh, 1/2 acre in pasture and 1 acre in scrub and saplings. the acre in scrub is a north facing slope and part of the bush acres is flat with good southern exposure.
should I convert the north facing slope with young saplings to pasture, or let that land revert to forest and clear a patch of flat forest for my pasture? The forest in question is 15 year old aspen, cottonwood
12300.
