I think its a good idea, tho i dont believe its a common practice. I love cinnamons but i know super cinnis can have kinking problems. So i got my male and female from 2 different sources and think i will trade up genes like every other generation just to see if it helps with my odds or not. I also would have no problem doing it with any other gene, as long as what im trading for looks as good as what i have to trade lol.
