you're not going to like this, but my Tibor Everglades is incredibly smooth, can be set very light & doesn't over-run...
i'm slightly disappointed with the Danielsson i have. the drag can't be set light, the settings aren't very well demarcated and there's a slight, but noticeable, inertia on start-up. enough to make you worry about lighter tippets on the take. it's a quality piece of machining tho'. the handle is very small and the drag knob isn't the easiest to adjust.
i have a Lamson Guru which doesn't look quite as refined as those two, but is actually really smooth. i believe the drag system is exactly the same for their cast models too? if that's the case it's a quality drag for not big bucks
my surprise find was a bargain Guideline Quadra (now discontinued) . incredibly smooth and very low start-up inertia. it's a cracking reel!
