I have smoked a couple blends of Cavendish, Lane Ltd, and Smokers Pride (also made by Lane) I found I ended up with some serious tongue bit. I know alot of cavendish's use quite the bit of PG to keep is sweet and moist. I am looking for a GOOD quality black cav that does not have any PG in it or bite. I find myself very sensitive to it, and have had a few occasions where I have had bite so bad it was like eating Jolokia Peppers. I couldn't enjoy the bowl due to the bite. I don't haul on the pipe hard, and avoid smoking outdoos on windy days, also all my pipes are opened to 5/32" draft hole. I have spoken to my doc about it and he said he smoked some cavendish that did the same thing and he found out he is super sensitive to high amounts on PG in certain blends as well, although he couldn't recommend any to me since he hasm't tried it since for fear of bad bite again. (Yes my doctor smokes a pipe 8) )
