You may also want to look into an all-mountain alpine board with hard boots. They are much easier to find/demo in Europe. I just made that move. It is a lot of fun. Carves are much more powerful.
Boots-wise my wife just gave me the Burton Imperial (11 1/2) boots for christmas. I am yet to use em, likely next week.
The Custom X looks amazing, but I am having doubts as to if it would be too advanced for me. A little intimidated perhaps as the last sales person I spoke to also seemed almost in awe of it
