There's a debate in the MOD thread about whether or not the 18z solution is feasible, well in my experience you can pretty dismiss any solution that hints at heights to the NW out of hand, even if future runs do go with something like that you just know something will pop up to derail it, the only time that wasn't the case in more recent memory was in the 09/10 and 10/11 winters which probably happened in an alternate universe.
