I have used the shove your rod tip in the water techique with success in order to turn a hot fish. I've seen others use it, particularly on the point at Blue Creek and it does work. Whether or not if your line is in good enough condition to withstand the pressure is a different issue, ie: nicks and chafes. When faced with an active, jumping fish, as in Summer run, I try to remmember to drop my tip, should a fish land on the leader, causing it to break or pull out the hook if it's lip hooked.
