Tiny 2x2 and too many fems...

Got myself in a bit of a conundrum. So I'm currently doing a test run for a breeder. I popped 8 seeds and low and behold turns out (sex test) that I now have 6 females to deal with. Obviously I can't run all six to maturity in my 2x2 grow space and don't have any place other than my 2x2 to grow. If you all were the breeder would you rather have me grow out 4 of the fems and keep them small or just pick a couple and see what happens with two? An advantage with growing 4 would be to bring out possibly more phenotypes? Or would it be better to just give two a bit more veg time to see what kind of stacking more mature plants would give me? Whats the call? I've run 4 in there before but it definitely gets a bit crowded but it can be done easily enough. I've actually sent an email to the breeder to see what he would prefer but wondering what the forum thinks? Heres a poll attached. And keep in mind this is a tiny 2x2 grow tent.

Take some clones of the others and run 2 at a time. Keep the clones alive, or clone them again while you wait. You definitely need a bigger spot for pheno hunting. I do 10 in a 4x8 and that gets tight, even keeping them small
