INW Custard and FA Caramel - they add a little bit extra caramel, while bringing a bit more body.
FA, HS and TPA Ry4/1 - TPAs all alone is dirty, but not tobacco-y enough. FAs is cleaner and that's exactly it's problem. Hangsen just to bring that classic hangsen tobacco note.
TPA Brown Sugar - i can't really explain but i really dig how it works with RY4d, makes everything a bit darker.
FA Mts Wizz - The mix didn't really work before i threw this in, just blends it all together.
A couple weeks should do ya. It gets a bit fuller the more you steep it, but starts losing some 'bite' after the 2nd/3rd week.
V2 Dropped TPA RY4D, upped both FA RY4 and HS RY1
