I agree, go with 2 UDS's! I have a double barrel and a UDS, and the UDS is sooooo efficient and easy to use. The double is great to use when you have a crowd, cause everybody thinks it's the coolest thing! It took me probably 8 - 10 cooks to figure out my DB, and one cook to dial in my uds!!
Actually, you should build 2 uds, and then build the db!!
You can NEVER have enough toys!!
