Re: what type of tobacco?
Most of the tobacco is Virginia. It's the most widely grown and therefore the cheapest. And IIRC it's lower in nicotine than other varieties. Brands like Starbuzz and the like probably use all virginia leaf as they wash the bejeezus out of it and cover it with flavors. Other brands like Nakhla, Salloum or Desi Murli have other types mixed in, but the exact amounts are trade secrets. You'll have to experiment some.
