Yes, I am not a fan. First off there is nothing og about it. It ads sweet candy to any cross. Never had hermie issues though.
I know a guy who scored loompas cut of underdog aka headband. Also runs ghost, TK, legend, sfv, and several other ogs. He claims the underdog is his favorite and intense og flavor and smell. Sounds like the opposite of jo.
Idk, personally I wouldn't keep anything for breeding if it was the complete opposite of the famous parent. I mean all the things that make loompas cut one of he best, it doesn't have, and won't add in a breeding. Then when you cross it to mother cuts that are legends. Chemd, Louis xiii, etc... Most would want a mother dominant pheno when buying beans. Jo makes sure you don't get mother dominant plants. It over powers and waters down the mothers. In my opinion not a good one for breeding.
