The camacho website states the havana is wrapped with criollo.
SLR is pinareno, but I do believe the filler and binder in a SLR is the regular corojo.
My point is that a box I bought (marked "MD" on the bottom) was really different in taste. All the SLR's I've smoked are really spicy, produce thick smoke, and are powerful; this one wasn't. I have some SLR torpedo's and some rothschild's (from another box) and there is a substantial difference in taste then the recent box I purchased.
The appearance of the wrapper is much like the corojo (thick, slightly veiny, darker then the usual SLR wrapper-even with the obvious variation expected from a different crop).
