Give it a try the next time you're out (unless you plan on pulling on a 100-pound tarpon). Even if you use a performance disc-drag reel, let it off a bit, not quite to free-spool, and start playing around with palming. After all, not everything you hook will be the exact same size or have the same energy. Also, water currents differ from spot to spot, so it's hard to dial in on an exact, do-all drag setting for every fish and every place. On top of that, in my guiding experience, a lot of anglers break off fish when they're fumbling around to adjust the drag setting. Better to set it fairly light, and be able to use your palm to slow the reel down (at least for trout) than to have the drag too firm, and hope you can back it off before you break. Palming the reel, even every now and then, will improve your fish-fighting senses immensely. That said, don't go overboard. If a performance drag will help you land a great fish, by all means, you should get what you paid for.
