I absolutely agree MG. I would certainly try them if it's all you had. Nothing saying green won't germ. They probably will, but dude has 500 seeds. He can probably afford to be picky about the seeds he chooses to start.
I believe that the tiger stripes can be a strain thing. Still a good choice. Any of the black or gray seeds you mention sound perfectly usable. If you have 400 seeds I think you will find a killer strain you like, and eventually, selectively pollinate some flowers to replenish your stock. You should be with seeds indefinitely. Are you saying you are worried about running out of seeds?
