Jeff, no such animal. As you know Cameroon leaf is used almost exclusively for wrappers and is very expensive. If you have visions of smoking a Don Carlos in your pipe I hate to be the bearer of bad news but it ain't happening. Now there are many blends with cigar leaf, but it is not like smoking a cigar. If you want to try one, I would recommend GL Pease Robusto.
I would definitely get a tin of Escudo, to me that was the blend that opened my eyes to how great smoking a pipe can be. I was a cigar guy also and Escudo was the first blend that stood out as strong and flavorful and didn't make me miss my cigars. GL Pease Haddo's Delight was another blend that helped in that regard.
