Halo has Tribecca,Torque 56,Prime 15 which are all sweet and considered tobacco flavors.
All excellent tobacco flavors, IMO.
Although I'd be hesitant to call them sweet. Torque definitely isn't sweet, almost rough and dirty at times but reminiscent of an actual cigarette.
Tribeca is somewhat sweet, maybe more rich than anything. The tobacco takes a backseat in this flavor with more of vanilla, caramel type taste upfront. It's very full bodied.
Prime 15 might be my favorite of the bunch. The nutty flavor adds a certain complexity to the tobacco notes. It's a great combination, but just mildly sweet and not a distraction from the robust flavor.
