Not bulk blends, but lately I've not been able to get enough of the Syrian Leaf. I would check out McClellands Three Oaks Syrian for a nice mild introduction to Syrian Latakia with some amazing sweet Va's and Orientals, or MacBaren HH Vintage Syrian if you want to step up the brashness of the blend.
If you really want to step up the Latakia content (but keep some complexity), I would highly recommend GL Pease's new blend, Lagonda. Kevin said it best - "...if this blend was a woman, I would marry it.".
For a Lat bomb that's more like a smoky punch to the face, try Hermit Tobacco's Captain Earles Ten Russians blend - just don't smoke it on an empty stomach! This blend has the added bonus that it keeps the mosquitos (and people) away.
