Crossing an unstable hybrid is just going to make the gene pool a whole lot larger. You're going to have a lot of phenotypes to chose from for many many years. This would be like 4 crosses for this pepper in only a couple of years I just don't see the point but good luck.
Its just a hobby to me,i love growing Chillies in not interested in seed selling ect just growing.I think people will just have to get used to the fact that there is going to be lots more folks trying to grow the hottest Chilli in future seasons. I must admit i will be having a go at it i find it a fascinating pastime.Imho this chilli growing hobby is going to become much more popular over the next few years,some of the sauce ive produced with Seven Pod and Fatalii the last few weeks are superb.
