I was just reading about the F1 crosses last night, I fell in love with the pimenta tiger cross, it reminded me of the pepper of death that Homer Simpson had if you remember that particular show, SW Virginia is zone 8? with a heated green house you could get two seasons which would cut your time in half.
I love the color of the plant and the pods, you could also out cross to a fish pepper that has stripes to strengthen the striping genes, but since its only mildly hot it might change how hot the pepper might be unless you selected for heat also.
At any rate really nice photo's of the pepper and good luck with your cross.
