First off i am posting this here cause i don't wanna ruffle everyones feathers like i would on one or two of the other sites..
Secondly there are a lot of guys who are better and more knowledgable than I am so take my opinion for what it's worth to you.. Thirdly i am human and that gives me the right to have an opinion
OK here it is.. A lot of people spend a lot of time talking about ever stinking tiny little detail of spey casting.. This style that style, this line , that line this much grains , that much grains,, this amount of angle change ,that amount of angle change.. well here it comes are you ready for all it?? It's all a bunch of B.S.!!!!
Buy a line that does the job you want then buy a rod that matches that line, figure out how you want to learn to cast and have fun.. The idea you need a rod with a different action for every different line or casting stroke is just a bunch of hogwash.. you can take an xlt on a 12 foot rod using a short choppy stroke and cast it just fine, likewise you can take a shooting head on a 16 foot rod with a long flowing casting stroke and cast just fine that way.. all the super technical spey junkie talk is just a bunch of opinionated B.S.... and that's the truth.....
