Before answering that question, one might ask what you're injecting? Fruit juices with seasoning, salty water with seasoning, ususally overnight to 24 hours. Injections with phosphates and msg, 4 to 6 hours. I also inject untill they jiggle like Jello. Volume is around 16 to 20 ounces. I personally like the smaller needles, around 1/8 inch maximum, placing inj.locations one every inch all the way around. I like the idea of wrapping , will try soon. Good luck. Steve.
