Hcigar..no doubt. Tobeco 91clond has great threads, but positive block is raised above negative block, and the insulator underneath looks like it was cut by a 5year old.. probably because it was. Plus, i had to file wick wells. I'm interested in seeing how the tobeco kfl+ clone is. Eh pro threads are rough.
When you get a clone..look at the base for your decision. This is a picture of tge tobeco 91 and some unknown lite clone. Tobeco on left, unknown on right, you want the wick wells to be somewhere in the middle with how they're cut.
