I think the timing for this was off. We just got done with the Christmas BOTM, which takes a lot of effort, and then people are usually busy with Christmas and New Year's stuff in December like traveling, shopping, and celebrating. Then to make a stock UHW which would also be a lot of effort... speaking for myself, I didn't enter because I didn't feel like attempting a stock UHW, though I might have been willing to throw together something simple like a LW.
I think stock UHW would be interesting to revisit sometime in the future when people aren't so busy though.
