Excellent post, Kousa.
My very rooky opinion.... On my short crosses, so far, I haven't gotten much that impressed me.
From a long cross, I got a few heart stoppers. I often wondered if I only did 5 to 10 seeds would I been lucky enough to get these few special seedlings. I once asked whether you can make a judgment from just a few seeds. Gossard replied that he got Heavenly United We Stand from a few seeds. In my opinion that was good luck, which he deserved.
