Depends on canopy. Full moon under lots of trees and leaves is still very dark, plus the shadow play hell seeing. I am a believer in NV over thermal. I can see what I am targeting with NV, but thermal can make it hard to tell. I hunt cow pastures with calves, goats and donkeys. I need to be certain of my target and what is behind it. Tried thermal and went back to my NV scope and monocular.
If I were you, I would ask your dads buddy what he recommends. Have fun. Also, always a good idea to scope out the hunt are in daylight so you know the lay of the land, where they should be coming from, and if there are any unsafe directions you should not fire down.
