Hey Dave & Husker -- Tell us how you smoke your jerky. You should have no trouble getting excellent results from your CS. I have actually cooked mine to a crisp - way over-done. Jerky snapped like toothpicks.
If you can explain your process maybe we can make some suggestions.
Personally, I get great results with bottom round sliced with the grain cut 1/4" thick. Use High Mountain seasoning & cure.
Pre-heat the smoker for about 15 minutes, using about 2 oz hickory. Three hours with the door closed gets me very close. Smoker is set at 200˚
When I open the door the first time I snip a piece off with scisors (sp) and test it and adjust accordingly.
