One addition for the tung vs linseed oil discussion, which also often invokes Flexner:

"If you were to choose between using boiled linseed oil or tung oil for your finish, I would think you would almost always want to use boiled linseed oil."


That is from this article

He's talking about furniture in general, but the principle would seem to apply that tung oil offers no real advantage over BLO on balance.
