Spinning Down (dice testing)

Today I bought what will very likely be my last set of Chessex dice. As I've pondered the games I might run over the summer (and hopefully into the fall), one of the things that I've considered has been the dice required for each. AD&D 2nd Edition, as well as my vivisected Basic Fantasy rules set, use the standard complement of polyhedrons. White Box, in addition to being available for free or at low cost (much like Basic Fantasy), is so minimalist that players need only d20s and d6s; it was these that I bought today, such that up to four players can use a d20 and a rounded spot d6 of the same color. (I might even give these as small gifts to the players, if they choose White Box and prove committed.)
