ball mills mess variations - waldemarpanek.pl
The 534 Mills Mess is a variation of the 534 (or Four Ball Mills Mess) in which the arm motions and throw paths of Mills Mess are applied to the 534 siteswap. Theoretically there are three different ways in which such a combination could be performed, but in practice most jugglers make the "5" throw under-the-arm and then go from there.
