MXE is pretty fucking cheap if you look around, and with the potency, like 3-4 times for a k-ish experience i could easily see this being done, fuck now that i think about it that would be really, really, really cost effective although super fucking dickish, k for me has always been really predictable, as in it seems to always lead to the same place. MXE on the other hand is all the fuck over the place, good, bad and meh often minute to minute. there are also plenty of reports in the PD big and dandys of the two being fucking horrible when combined. never had an unpleasent time on k, but mxe is quite hit or miss for me, especially when alone
