it dosnt matter... one team is FWB riptide and the other is SF riptide... teams send in multiple squads sometimes... Dynamic 1, Dynamic 2.. Dynamic and dynamic black.
Just make yourself longsleeve tshirts. Stay away from short sleeves because some places will go by PSP rules which i believe says you need a full sleeve. other than that just practice together as much as possible and all together watch as many better teams as you can. then just register for an event and have a blast
