I have an older non-RF offset. Hotspots, uneven smoke sometimes, etc. On my Lang RF; none of the above. If I want a variation front to back on temps, all I do is lower the front a tad. Dead even or ever-so-slightly higher on front an the temps are almost exactly the same front to back.
Hance - Lake Dogs Cooking Team - MiM/MBN/GBA CBJ and comp cook
Lake Sinclair, GA (strategically about an hour from darn near anywhere)
Started competing in chili cookoffs back in the 1990's and have competed in more than I care to count. I became a CBJ in MiM in 2005, then MBN and in GBA in 2010. I've probably judged 130+- BBQ comps (sanctioned and unsanctioned) over this time. That said, I really enjoy competing more than I enjoy judging, and hope to get back to doing 4 or 5 a year in the near future.
