Well, I didn't vote either but I can tell you what I use when fishing for kings in the salt. I use medium heavy drag setting and usually after the first two good runs or so I tighten it down a little more. My theory is to let the fish run but make it work really hard to do it. Then by tightening it after the fish is showing signs of being tired I am able to get it to the boat faster. I truly believe it not only whips the fish physically but mentally also. I too use braided spectra (powerpro) and have utmost faith in its ability to withstand a lot of drag tension. The biggest problem that I had last year was a day that I hooked 18 kings and smoked the drag on my Okuma spinning reel. I'll never use a spinning reel on a king again. I was actually fishing for pinks when the kings showed up and I switched from 10 lb power pro to 20 lb powerpro and used my rod I use for silvers which is a 7 foot medium action rod g loomis IM6 blank. After that day I looked at my rod and although the blank held up supurbly you could see where the guide wraps were a little stressed. I guess what I am saying is use a drag setting that your weakest link can handle or you will ruin something. The next day I went down with a proper set up and slayed the fish again but because I was using a longer rod I had to work a little harder because of the loss of leverage.
