I am a preferred 50-50 but use alot of Mountain Oak Vapors 70/30 tobacco's as they are clean, fresh and a very consistant flavor in the Ithaka. Such as MOV Gold and TNO. I also love Aluhsion's Rising Gold. I dont swing into the fake fruit flavor's at all but love the 100% real flavors, new MOV line and Aluhsion tea's.
