I recently did a first UDS cook with pork spares and a fatty. This was an excellent 1st cook as the fatty was ready just under 2 hours and the spares were finished in about 5.5 hours. The slightly fatty spares are also forgiving as well.
The shorter smoke time reduces the concerns associated with a first cook. I have since ventured out in the last few weeks to fatties, brisket, babybacks, chicken and corned beef with very good results...other than the corned beef that was salvedged for dinner tonight.
