For you guys who use a deflector, a question:
In my understanding, one of the beauties of an UDS is that the drippings form the meat fall into the coals and create steam. This adds some flavor back to the meat and helps keep the air from getting too dry. If this is true, do the deflectors keep the drippings from hitting the coals? Is this a problem? I've considered using tin foil with holes poked through it.
