You always put the spinna where you want the ducks shot. Also you may have differnet luck than anyone I hunt with but your success on geese with a spinner is likly to suck. They dont like the spinners at least anywhere Ive hunted them. You will get the odd one but most will not work in with it running.
....its like taking x-lax when you have a bad cough. It wont clear up your lungs, but it sure stops you from coughing
