The Bauer Supreme 70 might be an upgrade, but I am unfamiliar with the skate. Is the inside microfiber or leather and cloth? I read that they have exterior this and that with the heel support, but that seems to be a bunch of jib jab. You should want interior heel support on any skate you get. I think that you are probably sitting on a gold mine with what you have now. Between baking them, and upgrading what you have you have one hell of a skate. See how they last, sharpen them to the three-quarter inch cut every fifteen to thirty uses, and make up your mind after this season. You spent under $200.00 on brand new custom skates. Not a bad bargain. If you really hate them after your season, hell with it. Keep them as a backup and try a wider boot. I have a feeling you are very comfortable in what you have now assuming everything is complete.

P.S. I will post a picture of my skates this weekend when I have time. I use Mission Fuel 110 XPs on the ice and Mission Proto VI for roller. Both are pretty sick.
