I train Jasper with a Sit Means Sit shock collar. It works well for us. Jasper has almost completely stopped humping now that I can stop him in an instant before he gets "into the groove".

Like you said, everyone needs to find what works for them. Have you read Cesar's books? A lot of his materal does make sense - dogs are dogs, not people...they need a lot more exercise than the average person gives them...having a calm, relaxed attitude while working with your dog will achieve results that you won't see if you are stressed out and strung out while working with your dog. I don't like all of the techniques he uses, but a lot of what he says rings quite true to me, especially about under-exercised American dogs. I see them all the time in my store.
