Cotton Boll is the strongest rope I’ve tried, made in the States mainly for chewing but pipe smokers got ahold of it and turned it into a pipe tobacco so to speak, it’s damn strong, stronger than the Gawith ropes and would surely think it would satisfy a cigarette smoker, I’ve been dipping Copenhagen for over 25 years and Cotton Boll gives me a buzz. Forget where I bought it but if you Google it you shouldn’t have any problem finding it. I just offer this one as a suggestion for strength as I much prefer the Gawith ropes, Brown Bogie and Brown Irish X being my favorites. I can’t stand the black ropes, tastes like charred meat to me. Coconut Twist is another favorite but it takes forever to properly dry out because of the heavy oils. I usually leave it out overnight and it’s still nowhere near crispy but it does provide a rich, very English tasting smoke, it’s great stuff.
