By "Black Cavendish," are you referring to Lane's BC-A? If so, I really like it. I also like McClelland's Vanilla Black Cavendish.
I started smoking a pipe in January, so I'm still trying to sort out what will work for me. As part of a large ($250) tobacco order from pipesandcigars.com, I bought 4 oz. of Haunted Bookshop because I had read so many good reviews about it. I tried it yesterday morning, and loved the aroma and taste, but it bit my tongue in an awful way, even though I was consciously smoking at a moderate pace. Later that day, I thought, it cannot be as much of a biter as I believed, so I tried it again. Ye Gads! I could not finish the bowl.
Obviously, Haunted House is considered an excellent blend, but not for me at this time. But I do quite enjoy BC-A and VBC.
