The only thing is that they're from different sellers and for the last 3 I'm getting a deal if I get the 3 together. Also, I have to pay to have them sent from across the city since I don't have a car. It's not a whole lot to ship across the city but it just adds up buying from multiple sellers that each have to ship from different locations.I'd go for 1 and 3. The nuclear greens are easy to come by and look very drab under white light. I think 3 is what they are calling salted agave, which look great under any lighting. 1 probably looks drab under white but it's still probably interesting over all.
The platygyra/maze brain looking one would be my pick from the second batch.
