i know i find peoples obsession with stability amusing. i like f-2s i can pick what i like clone it make moms or work it through a few generations to get what i want. if your doing an sog grow or commercial grow then uniform plants are nice but again thats what clones are for.
I like F2s also, just don't feel like paying a stabilized line prices for them.
In my 87-88 SSSC catalog (my wife cleaned and I haven't re located it yet), there were ~25 or so strains listed. They were very careful to tell which one were stabilized, F2s, a couple of untested F1s, and which had a tendency to hermi (both sativas).
Now, you don't see that much and there are also literally thousands of strains. Well, thousands of neat names anyway.
Creating F2s from 2 stabilized strains takes little skill, not much of a step above pollen chucking, but then charging big $$$$ and then advising to 'pick the best pheno' out of 10 seeds?

50 seeds perhaps, 100 is better, but 10?
Guess there is more than one being born every minute.
bicycle racer, this rant is not directed at you, please don't take offense.
