Something a little different to the norm and being vague here as I am not sure what is available without direct importing them which is not really feasible.

A few of us have been enjoying Esmeralda recently but I know getting some to roast is not likely :( So something along the lines of a more dedicated manual brewing bean with a lighter more floral or citrus note to try past our roasters. Costa Rican La Angostura was excellent from BBB as well.
