most people like me have a distaste for buying fem product at a higher sale price, i think fems are worth less than regs, the market disagree's. All you need to do to call yourself a "feminised seed breeder' is have a bunch of female clones and some good ol colloidal silver. no real selection process, no chance for future breeding, what you get is as good as its gonna get, or as stable as it will ever get.
now i think the method of using CS on a female is actually enlightening, as the sex parts YOUR desired pheno produces will have alot of resemblance to what you might actually want in a male (ie desplaying the male traits in order to make selecting the keeper male easier). but i guess i'm one of the only people who thinks this.
