I know nothing about them, but I suspect that your money will better spent on a better model Moeck. In particular, if the Carlton price is low then the quality is unlikely to be better than the student level Moeck that you already have.
Moreover, with your better quality treble upgrade you should look for a better quality wood than your student model. Call one of the good stores, e.g. they’ll give expert advice.
