wow. OP isn't the sharpest tool in the shed. Someone wants to pay more for a car they haven't seen in person. attempting to pay you via check, no contact other than text. **** might as well be stevie...
by far out of those three for me personally was 1MR Vortex, i tried the Curse and had an insane headache. C4 is another good one but 1mr takes the cake with clean energy and extreme focus. good luck
