There are so many, much like cigars. For aromatic blends, I like Cult Blood Red Moon which is a cherry flavored, Nutty Irishman, Autumn Evenings and Eileen's Dream (CAO) the best. There are many I have not tried. Of the non-aromatics, I really like English blends like Peterson's Early Morning Pipe, Bijou and Vieux Carre from Cornell & Diehl. One other interesting blend is called Penny Farthing from GL Pease; it is a shag cut that smokes well. I am smoking a Virginia/Perique called Orion's Arrow which I like but not as much as the English blends that have Latakia which gives it a smokiness that seems, to me, to make it a little smoother smoke.
How about you, have you found some you like well? The varieties seem endless, so I will likely be trying more in the future.
