from what ive been reading all over the net is that there are 2 different headbands.one is og kush x sour d x master kush.the other one which you can buy here in northern cali from oaksterdam catalogs is 707 headband,which is og kush x sour diesel then back crossed again with sour diesel.
so i think there is confusion over which one is which.headband and 707 headband.two different strains.
