ill put my 2 cents worth in i reckon it has to be based on the situation as i have had good lesson in my time and i learn evey time i connect with one, but i was fishing in thick tree area and i got smashed by a barra she ran me into one snag which i lucky enough got her out of (with a bit more drag pressure) to help him along but then he decide to go into the oppisote direction and i was down to 3 winds of line on the spool i quickly cranked the drag and drove into to her i reckon that is the only time you need to do that i reckon if its the last resort i belive more pressure put loads every thing up and eventully a weak point will be found under strain and bang fish gone
just my 2 cents worth
