It looks grrrrrrreat.
BUT
How practical is it? I'm not going to try sliding ribs, a butt, a brisket through the side. And when it's done, I am still going through the top. I don't need to peek, so really, whats the point?
Most (all?) mods I've seen serve a useful purpose. Unless your point was just the "bling" factor, I don't get it.
Looks cool but it's like putting pearls on a pig (not that I'm saying the WSM is a pig). IMO.
