Hmmm, tough question. With the SR strains introduced by Sara to the masses I am not sure what is not available in the states.
I do especially enjoy the 7 Pot Jonah, 7 Pot Yellow, 7 Pot Orange, Red and Yellow Congo also.
Basically I am clueless as to the legitimacy of any of the 7 pots already available here in the USA. So if you have a reliable source from inside Trinidad I would start with finding the common household peppers that everyone uses. I'll be following this thread as I am sure others will chime in with first hand knowledge!
cheers
