I would only sell those 4* for a very good reason, but it's hard to say anything specific without seeing your roster. You should put your roster on gamependium, so it's easy to reference to in the future if you have more questions. I'm still going through my 3* transition, so I'm not much of a veteran, but these are my 2 cents.
