Pushing is when you control your depth with a weight....we use 3 Oz. Pulling is when you do not use a weight and control depth by speed and length of line out. Trolling is what we call it when we spider rig.....but all three forms are a type of trolling...and longlining....you control depth by speed and length of line out also. Running crankbaits with planer boards is really pulling.....just got them out away from the boat.
