I'm not aware of (probably from being American) of any blends with Cuban tobacco. is it that all Cuban tobacco is straight Cuban tobacco? i always wondered what a hybrid good smoke would be like.
if i could choose a few, the Dominican opus/anejo blend with Trinidad's blend!
or tat's Miami...
There are a few NC brands that still really do it for me, but for the most part, CCs for me... There is just more subtle complexity in the blending, where NC blending (not entirely, but largely) is heavy handed to say the least.
I saw c&d sells a baccy blending kit that come with recipes. Just an fyi. Just started to get into pipes myself and can't wait to start blending some stuff out. Your English looks and sounds fantastic. Keep us updated on all the goodness you're brewing up.
