Nader, there both international releases. they tend to sometimes releases an international ball from the same line they make in the US but not every ball or every series makes the cut. like the Bank series there was a bank of 900 Pearl and a red and silver bank roll. the bounty series there was a purple and black bounty and a solid black bounty ball released overseas. as well as the Hack and hack infect series the Break series had a lot of overseas balls made as well like the prison break day break and blue Jay. for the most part there the same cover and core just different colors which I think sometimes the overseas colors are much better looking but thats me. as far as i can tell the dream and dream tour has the same #s but 1s a solid the other is a pearl and the same with the Moxie and pro moxie 1s a pearl the other is a Hybrid cover.
