Never seen the Duel 50light, but I fish with a Duel Speedy 12 and 20 for grouper in Florida when I visit mom. The have a really smooth drag system, helical gears, and feel like a tank...they are as solid of a reel as one could get for it's size. I have used them over the past 6 years, and sent them out for service 2 years ago... they came back buttery
As far as lever drags go I love it, however I'm a star drag fan, thus it's location now (Florida) only to be used 3-4 trips a year. I got them on sale for $220 each a while back online right before they did some minor changes (handle style,etc) for an updated version. I bet the 50L is a quality reel much like my speedy's... We Italians don't cut (too) many corners
Let us know what ya think if ya get one.
Dom (Macchiato for me, please;)
