Good analogy Rick!
I honestly think every lily bulb is probably virused to some extent. All these bulbs come the same places, from the same grounds and the same gardens. It's inevitable that there might be virus in our own gardens, just not showing signs of it. Some lilies can tolerate virus better than others. Sometimes weather or stress can show symptoms of virus as well. I do think the pink OTs seem to be more apt to show both signs of stress and or virus before others though, along with the red and purples in second.
Again, it's my opinion though. Now if I had something that was completely mottled and the color was streaking and extremely bad, then of course I would dig it up and toss it. And I remember Lorn always saying to look at the reverse side of the bloom to see if the streaking showed on the reverse, then it was a high probability it was a virused plant.
