How fly lines are made

of course there’s a lot missing but then we wouldn’t expect a line company to openly share proprietary secrets. however, this short film from Rio gives us a good and simple insight on the making of what’s the most important element in the fly casting system: the fly line.
every manufacturer will have their own variants, profiles and special ingredients that make them unique but the basic construction is the same. enjoy !

Floating Lines and Strike Indicators

by Brian Chan via Rio’s blog Tips, Guides and Resources

an awfully nice article on stillwater tactics sure to help in this not-as-easy-as-it-looks environment.

” The reason indicator fishing is so successful is based on a little lake biology and trout feeding behaviour. The most productive trout feeding zones in a lake are the shoal or littoral zones and the edges of the drop-offs. Limnologically, the shoal zone is defined as that portion of the water body where photosynthesis can penetrate to the lake bottom and allow green plant growth to flourish. This typically means depths of less than 20 feet. The shoal is the grocery store in the lake. Trout come onto the shallow water of the shoal to feed on aquatic invertebrates which are living in the vegetation or within the benthic zone of the lake. Feeding trout can be very specific as to what depth they will eat their prey. For instance, if a chironomid emergence was occurring in 18 feet of water it would be common for the trout to be gorging on the pupae between 17 ft and 15 ft. Suspend your pupal patterns above or below that narrow 2 foot zone and you will experience far fewer bites. “

Depth of Penetration

or rather…   Depth of Presentation – By Scott O’Donnell
via the Tips, Guides and Resources section of the Rio’s Blog

“The next thing to understand is how the line/leader/fly combination interacts with the current flow. A great way to start learning this is to fish a dry or waking fly that you can actually see (rather than imagine) and watch what it does in different current situations. I had fished a sunk fly for several years before I tried my hand at dry fly fishing. I realized immediately that my wet flies weren’t always doing what I thought they were. It was huge for me. Translating this knowledge to the sunk fly does get a bit tricky because of the added dimension of depth.”
 “When you add the infinite number of possible combinations of sink tip lengths and sink rates, length and diameter of leaders, and the sink rates of flies to this already complex formula, it becomes obvious that the art of imagining exactly what the sunk flies are doing can never fully be mastered.”

some awfully nice, well-explained priceless tips on swinging flies in Scott’s must-read article. it’s also a real treat to read an expert embrace the idea that mastery isn’t part of the big picture.

Rio Spey Line Recommendations 2012

” A newcomer to spey casting would be forgiven for peeping into this sport, trying it out, or listen to the many different opinions out there, and then turning tail and running away from the mass of confusion.

There is a mind boggling array of theories, techniques, tackle and styles, and it is very difficult for the beginner to make head or tail out of the world of spey casting. To explain the subtleties and intricacies of this spey world would be like trying to explain the rules of cricket to the average American, or of baseball to the average Brit. However, as fly line manufacturers, we only need to make it easier to understand the fly line – the most important part of your tackle. “

Simon Gawesworth, fly line designer at Rio just updated his spey line recommendation chart in this new pdf : Understanding Spey Lines 2012 

it’s often a debilitating experience when it comes to choosing the right line for the right application, this easy to read chart should help demystifying the process. Simon is one of the best Instructors and casters in the World, his shared experience is invaluable to anyone interested in the craft of casting fly lines.
