I've seen highly experienced GT fishos highsticking - its just unavoidable when fighting a fish at times.
I have also seen jigging and popping rods subjected to the most horrendous abuse against the rails of the boat notwithstanding the best efforts of the fisherman to avoid it! I had this at Shoalwater recently when I was fully locked up including having my hand on the spool and I got slammed. Almost got slam-dunked as the mongrel thing actually managed to lift my feet off the ground when it pulled me tight against the rails.
The drag was at an obscene level but if I didn't hold on for dear life, the fish was a goner and as it turns out, I still got my butt smacked
