I'm not really in to RY4 anymore, but I figured I'd mess around with it.
Initial thoughts: true to the name, it tastes like a pretty typical RY4 with some smokiness. The smoke taste is almost phenolic this soon after mixing. Hoping that settles out after a while. I can't really stand vanilla anymore since I overused it when I first started mixing, but it's good enough for what it is. Would probably taste better without Vanilla for Pipe. INW Desert Voyager tastes pretty identical to TFA RY4 Double to me, so that could probably carry the RY4 part of this mix on its own. I think I'd enjoy it even more if I cut everything except the Black for Pipe and DNB (lol.)
