Looks like a nice place for deer to transit now that you have cleaned it up.
Do you own a brushcutter? I have a Husqvarna 345FR just for situations like that. You clip it into a harness so the weight is on your hips, rather than your shoulders and back.
In addition to working on slopes, I use it for small cedars. I used to have to cut several branches before I could reach the cedar trunks with my chainsaw. Now I can just walk in with the brushcutter and get most of them with one swipe.
