I'm always dicey on the line between a Balkan blend and a regular English blend, but my all-time favorite full latakia mixture is GL Pease Westminster. It's superbly balanced, and always gives me the same satisfied feeling as eating a big bowl of pasta. And to top it off, it's readily available and pre-deeming date.
As far as a blend I dislike, I would say I don't ever intend to buy any more of Abingdon. It sacrifices a lot of Westminster's balance to achieve a little more fullness, but to me it's not worth the trade-off. Not bad, and many people love it, but it didn't flip the switch for me; not after I had experienced nirvana.
