@kwf Hey, I've been following along a long sporadically and enjoying it thoroughly. Maybe you already mentioned this, but it occurs to me that because of the volume you're doing, I assume you are grabbing other instances of less common variants, for trading or bootstrap purposes? If not, you might consider it. You could basically give some kid a starter kit that gets them 80% of the way there out of the gate, etc. Heck, I'm tempted to commission you to start making a set for me, since you're going to all this trouble anyway.
