Khangs starrburst was the reason I bought Bahamian goat seeds. Really cool cross he made!
Even if it somehow wasn't possible to make this cross, you made a good call getting Bahamian Goat seeds. They're delicious. Plus he's halfway done here. Though he has sent seeds out to some people (which I wouldn't because of how the Chocolate Bhutlah situation), I'd wait on the F8.
It'll be a stabilized strain and we'll all be able to enjoy some 400k to 500k scoville greatness.
