See if you can fit into a size 12 in a boot like the hail. I wear 12.5 to 13 sneakers and size 12 hails. I could probably do 11.5 after they packed out. Other boots on the market also minimize foitprint and let you go a little smaller.
I have the 09 x and have been up around 250, down to 190 and back up to 230+ since owning it. You wiil be very happy with it. Custom is a good deck also but not as great as the x for that type of riding.
