Ok, I guess I have to say that I disagree with both Gary and jBotti.? This is one of those areas where value becomes more important (to me, at least) than price.
In my opinion, by this point, Billy should know more about you as a skier than you know about yourself.? He should have almost all of your knowledge about yourself (where you ski, how you ski, what you like in a boot and a ski, etc.).? He actually knows more about you than you know about yourself, because he has probably observed things about your anatomy or physiology (maybe those are the same thing) that he filed away but didn't necessarily point out.? He may, in fact, have observed things about your boots but didn't comment because people in the customer service business learn quickly not to bad-mouth what the customer is using.
My advice would be to talk to him and see what boot he would recommend for you.? Or, just as important, what boots would he recommend that you stay away from.? If it turns into a discussion, you can share your thoughts and Gary's thoughts and JBotti's thoughts, but I would start by picking his brain rather than putting him in a position to discuss boots in the framework of your considered options.? (By the way, I think JBotti's plug boot recommendation makes sense for the skier you probably are, even if you want a softer plug boot).? And, by the way, you have someone that knows what to do with a race-like boot (based on your description of his background).
Anyway, my summary is that when you find a "trusted expert" then rely upon and trust and seek out his expertise.? If you wind up paying MSRP for a boot he recommends, it may still be a great deal!!
But I still think Lange's have too much forward lean and I absolutely believe Harald's assessment of rotary boots as a negative, and I really like my Head RS12's more upright geometry.
