Sorry for not exactly answering your question, but I am actually thinking of purchasing a number of alike wedges before the end of the year so I don't have to buy any conforming wedges for quite some time!
My understanding is that all wedges will be conforming from the new year so if you want a box grooved, milled face, ensure you get it before december!
