DS: Compulsion and the end result, is it worth it?

I use compulsion. It helps eliminate the grey areas. Compulsion, corrections, consequences are all the same to me. Once the dog has an understanding then one doesn't or shouldn't have to use compulsion as much. I see it as making the dog understand that he must make the right choice. I also train for the ring. I use compulsion for more then the retrieve. Compulsion can correcting for a no sit by positioning with the leash; reminding with a tug on the leash that over means to jump that jump; etc. Done right compulsion doesn't create fearful dogs even on "sensitive" ones.
