I hate to break in on it this way, but I only see 5 rounds here... there's 7 in a full set - grey, yellow, green, blue, violet, red and orange.  Do you have the blue and violet ones also?  If so then I'm also watching this intently.

And, anyone happen to have a violet one they'd be willing to sell? There's a few floating around and hoping someone has an extra they'd be willing to part with.
