People learn new skills in different ways. In my personal case, learning —and not only about casting related issues— has always been based in the understanding of how things work, without that I feel lost. It is Mel Krieger’s old engineers versus poets dichotomy. How much you want to dig into the physics of casting is up to you, but in my view even poets can benefit themselves from a little bit of knowledge in that department. Understanding the underlaying mechanics allows you to self-diagnose errors in your technique; moreover —analysis being the very basis of casting instruction— a solid grasp of casting mechanics should be a must for all instructors..
In any cast of the roll family our line is folded in two at the start of the delivery cast, forming a characteristic line configuration known as D-loop. This special shape, and the fact that fly, leader and even part of the line are already in the water prior to the delivery cast, set up a particular scenario pretty different from that of an overhead cast. That significant difference makes Spey casting mechanics worth of a separated study to delve into its very important —and, at times, overlooked— implications.
Overhead fly casting mechanics looks tricky; Spey casting seems to add even more confusion to the scene. But is it really that difficult to grasp how and why the casts of the roll family work? Well, it actually isn’t!
It is with this approach in mind that I have started writing this series about Spey casting mechanics: as a way of explaining it to myself in the simplest from for my own casting and teaching.
