I have the bubble box, i have a lot of shake, and i see a GRIP of bigger heads that will not go thru the 120lpi screen, i rubb and i have put 5 quarters, a wicca card, and a bubble man card to knock things around, anyone got any techniques? i also put my box in the freezer for a couple hrs before i start shaken things up, and my... i get a crap load. i have access to unlimited trim pretty much, so yeah but i'd just like to get the bigger heads =) thx!
