If you want to stay away from the Kentucky forward blend, but nic heavy, or heavier, I would suggest, as others have, Irish Flake. Squadron Leader is good too, but hard to find, and harder to keep lit. For serious nic, HH Rustica, Tambolaka, Mammoth Cave (or any twist chew, but requires a good dry time). You can also order Nicotiana Rustica leaves from Leafonly. They are surprisingly mellow, but not very flavorful. Keep away from children and pets. If you don't like it, make a tea with the NR leaves, and spray your plants for a powerful insecticide.
