@charlie That sounds like a great combination. You will be fine without ECA, carrot fiber and sure gel. These products help to create a moister product with a better mouth feel but I have made plenty of snack sticks without additives that were great for friends and family. They might have a shorter shelf life but I am sure if you follow the directions you will be happy with the finished product. Remember without encapsulated citric acid you will need to hold them in the refrigerator overnight before going to the smoker. Good luck and most of all enjoy making your own snack sticks!
