I mix it myself. 60/40 pg/vg, 20mg nic, 20% FW blackberry from HDV and 8 pippette drops of Wizard labs Marlboro to a 30ml batch. Fruity, smooth, slightly smokey and nutty. Great fresh, but even better by the end of the bottle. One of these days I will make enough to do a proper steep. Vaping friends all agree it is better than the juice they buy and I have converted a few smokers with this blend.
For a commercial blend, I really like Sweet Carolina, but its too spendy since I make a great one myself.
