for what its worth, many people i know have tried both (socal - 626) and they say theyre comparable, not much of a difference. it seems like lots of dealers here are getting both presses in bulk, so im not too surprised you have the option of either one or the other. most people i know have your choice options.
to be safe, id just go with the 007s. i get the vibe theyre lower dosed than the kappas, but until we see lots of user reports on the purple kappas (or an actual edata report), the whole "meth" rumor (from the greens) is going to leave the pill with a stigma...even if its completely unwarranted.
