although not on your list and I understand your explanation of the MX boot issue but have a look at the new drystar Tech 7, they are very comfortable boots and waterproof, I wore Tech 10;s for years and it does not take long before they break in and peg feel is just fine, the Tech 7 are better in that regard, I made the monstrous mistake of getting some SG12 about 6 months before the Tech7's were released, not that the SG12 are bad but I would have had the tech 7 in a heartbeat.
