Jaysin, you would have to order from Mr. Snuff, but I highly recommend you try Revor Plug. I think it would fill the bill for you. That is, if you don't expect a true old English tobacco to have Latakia in it.
The new GL Pease article, on this site, has this question asked and I believe Mr. Pease provides some recommendations. It's a good read either way.

I don't know that classic English mixtures did NOT contain latakia. It was my understanding that the British just didn't name the latakia in their mixtures but rather just lumped in under that "Oriental" moniker. Some blenders used it in their Virginia/Oriental mixtures and some didn't.
From what I understand, the British purity laws just forbade the inclusion of flavours other than natural extracts which is why the Lakelands are so floral and herbal. With a lack of ways to instantly flavour and sweeten tobacco the British turned to processing like stoving, pressing toasting etc and to naturally fragrant tobaccos like Orientals to flavour and make distinct their individual mixtures.
It's kind of like someone telling you that you can't use powdered oxo type broth or heavy amounts of salt in your soups. You will then turn to ingredients and methods of cooking to yield tasty soups. In my opinion the use of ingredients and processes to bring out flavour yields a better product than an instant flavouring. It also makes a better cook, or in context, tobacco blender out of you because it forces creativity and passion for flavours and textures.
@ cortezattic: Yeah I have been telling off high priced businessmen and lawyers and pointing out their ineptitude all morning so I'm all fired up. I just love the look on their faces when I open my mouth and they realize that the guy sitting across from them in Carhartts and work boots is an educated man who can see through their appearance and expects results. Never let 'em see ya comin'!
