If you are thinking about the 19mm just to reduce the cost, you probably won't be happy. Save a little longer and go for the 35mm ...
But if you really need more FOV because most of your action will be INSIDE 100yds ... then you'll be happy with 19mm (22 degrees of FOV). If you're strickly going after yotes, I would suspect your avg engagement range might be beyond 100yds, but that totally depends on your terrain.
The 35mm has 12 degree FOV on 2.5x magnification. About perfect for night hunting.
