I've been fortunate that I haven't found anything I "hate" yet (give it time, I'm sure), but I have a weird love/hate thing going with this shop blend I picked up the other day. It's an aromatic (cause that's what I like) and it smells GREAT, but it's just wet, wet, WET! I hate to touch it when I load my pipe. I usually let it dry a bit and I'll "puff" on the pipe unlit to hopefully help dry it out, but once lit it tastes wonderful. One other thing I dislike is how it tends to pop a little as I get about halfway through the bowl. Weird stuff.
