Well, I'm glad I could help! Good luck on your walk. Oh and if all they have is green, even though they don't taste as good (another one of my opinions) it should still prove to be helpful. Remember, the riper the banana, the more helpful for C... it would only make sense then, that the less ripe, the better for D.
Let me know how you do!
