What Cookshack model do you own? By chance an FEC100? Could you be a bit more specific when you say that the final product coming from the Cookshack does not compare in taste than from your Lang 36 patio deluxe? What exactly are you saying the difference is?
Now, let me say that I smoke quite regularly on a Lang 60 Deluxe as well as a Lang 108 Deluxe and the butts/briskets are moist and the taste is outstanding.
I am not sure if you have watched the Kingsford BBQ Pittmasters Championship on the Discovery America channel on TV where Myron Mixon, Tuffy Stone, Aaron Franklin and others have been judges but on this years final episode all three contestant were required to smoke on a Lang 60 or 84, can't remember which but the end result was that the final winner for the $50K prize won with the Lang.
Now, an interesting note, however, was that a well know National "Q" Competition Champion who is on the circuit big time is a guy by the name of David Bouska from Buthcher's BBQ in Kansas. www.ButcherBBQ.com .
David was one of the final three competitors and he swears by and has won all of his long list of "Q" Championships on a Cookshach FEC 100.
I have never had the opportunity to smoke or use an FEC100 to make any comparisons but I can say that last year my wife and I attended a huge restaurant suppliers show at the Orlando, FL Convention Center and Cookshack had a booth there. They gave away samples of brisket for people to taste and it was extremely good.
I will be most interested in hearing what your experiences have been comparing the two smokers and the difference in taste of the same items smoked.
