I personally do not think so. In my opinion, you will make a lot more off of a visual bred to hets than het to het. In het to het, your chances of producing a visual are lessened, and all of the hets are possible hets, so they are tough to sell for anything but normal prices. In visual to het, your chances of producing hets are higher, and all the normal looking snakes will be hets, so you can sell them easier, and at a higher rate.
