5) The Look. Let's face it, the reel spends most of its time as a holder of line on a fly rod. The sharper it looks, the more some people like it. Aesthetically, the Hydros SL is intriguing and alluring. I like the gender-neutral color and finish. And it's not over-engineered for looks to the point that it isn't functional in the hands. Easy drag adjustment, and a light frame top it off. The trend now in fly rods is to optimize feel, and a light reel, like this one, only enhances that.
