Of course it depends on your goals but.. In my opinion using as many males as possible is the best when working with outdoor genetics. Every year is different so it's good to have a lot of variation in there to make sure at least some plants flourish each time. I wouldn't even be too quick in leaving out those males that don't seem quite up to your standards, if some season is very different from the usual those genes might be the ones that shine.
This time I kept only that one male shown at last post. I usually go with feeling when selecting males (trying to keep all realities in mind). I just did not liked other males as lot as this one and ended up to keep only it.
I think it is more important to use more males when cross starts to come stable. Next generation will still give variety of different phenos, even used only one male.
Of course it would been safer to select some other males this time too, but in other hand it might be good for stabilising in small gardens to have smaller (but healthy) genepool. Like a betting to selected ones, sometimes you lose something and sometimes you win something
I see your point quite clearly anyway, but you might confuse a bit to situation where cross is somehow stable, this is first generation of cross of two different strains. If don't do any selections now and later it can end up to quite anything. In your theory way deeper you should keep also as much females as possible
Some general questions are how much you can stabilise before genepool gets too small or how long it is possible to regenerate something from small genepool?
Also I'm not sure how much of traits come from genetics straight and how much come from mutations. I mean if plant is not likely to survive outdoors, would it try to change its genetics somehow? I have readed mutations are happening all the time, but only few of them stays.
