I currently own 4 stashes with the "standard" colors (Red, Yellow, Green, Blue) - and would like to buy a fifth set to play TreeHouse. I know the standard extra color is black, which seems good, but I'm wondering if clear might not be better (and cooler!). Which one would work well with other IceHouse games, or is there really no difference? Thanks Derek -- This message is subject to the CSIR's copyright, terms and conditions and e-mail legal notice.
