I have a Loomis GLX 11'6' 8/9 weight rod that, according to Loomis, is built for overhead casting with standard weight-forward lines. I am interested in learning how to and using the rod for Scandinavian-style two-handed casting -- "underhand" casting. From what I have read and seen on the Rio "International Spey Casting" video, shooting heads are used for this method of casting, but I don't know what length or weight heads would be appropriate for this rod. Does anyone have any experience using the 11'6" Loomis for underhand casting and, if so, what lines (type and weight) do you use? Would a SA "Pike/Musky" taper line (35' head) or Rio "Quick-Shooter" (32' head) be suitable? If so, in what weight? The reason I am asking about those two ines is that I don't like using heads. I prefer intergrated lines. Thanks in advance for your help.
