Hey Storm,
I am a Raw NFG when it comes to this so please take this as a grain of salt.
From what I have read in this forum it's all about the low and slow, in other words keeping the temps where the meat is parked at a low temp..215-250 or so.
Using the minion method of starting your charcoal basket seems the way to go. Also place your "flavor wood" scattered in with your charcoal.
Like I said I am not an expert, but by reading though these forums and seeing the results, when my Uds is done I am convinced this will work.
Hope this helps, and I am sure a bonifide, certified, smoker will chime in.
Take care, and keep the 2 wheels on the ground!
