Interesting discussion. At this point (still amateurish) I see the merit of both but definitely will pay up for mini colonies.
There’s a limit though. I don’t want anything that’s overgrown a tile let’s say but a fully encrusted frag with multiple branches (mini colonies by some standards) is like the sweet spot. It’s not so big to where it’s adapted to a specific environment and will be succeptible to shock or a new system. But it’s not so small to where it will just die for no reason..
Another aspect, I really have appreciated the growth differential of one year between a mini colony and a small nub. There’s a compounding effect in SPS growth where you will see a LOT more quicker with decent sized frags, cause sheer math (% compounding).
Long story short.. yes I would pay more! To a certain extent!
