They also sell 30gr Pyro Pellets, I'd do a 50 and a 30. 80grs does'nt have that much recoil at all. My Wife is only 5'2" and 110lbs, one year I had Her set up with that 80gr Load and She shot it just fine.
I'd feel much better with 80gr's vs 50grs even at shots 50yds and under, remember anything can happen especially if the shot is'nt a perfect one.
