Simon Gawesworth, do you know him? Maybe not but if you are fishing with a Rio line, there is a very high chance that he put his hands on it. Not physicaly but Simon is the Brand Manager from Rio and he decides with his team which kind of fly lines will be made and sold, what their shape will be, how the coating should feel in your hands, how they should float or sink. Simon is a passionated with his job. Once at the EFFTEX we had the luck  to meet him with Jérôme Servonnat, he was kind, nice and easy going, we liked him instantly.
