while there is a market for caramels many have said they are getting harder and harder to sell. People don't want to deal with the sub-fertility issue or the kinking I guess. So with that said, I would say making pos hets not really something to strive for. I could see breeding to your pastel however. Sometimes het clown is more visual than some inc-dom morphs, so if that ends up being the case, you can hold them back and prove them out yourself.
