Particularly the Burkie 8143, which would be my second choice to the Winston BIIx 7/8 13'3" rod as a sweet scandi rod. The third is the T&T 1307/3.
As for "not knowing of what I speak" regarding the Rio
AFS S4 sinking shooting head for STEELHEAD, you are probably right. For west coast summer and fall steelies in the rivers I fish, (Deschutes, N. Umpqua, Trinity, Klamath)the fish are looking up and the water depths I fish are usually 4-6 feet deep so getting down 1' to 2' in depth is usually plenty this time of the year.
I found it less than satifisfying to have to go through the histrionics of a three step cast (roll cast to get it up, a short cast to get direction and load and then a third cast to shoot the line) to cast the AFS S4 line I couldn't see to mend (the line is black) after it hit the water. Why not cut to the chase and use a skagit line that I can single spey up in one movement and then forward cast? Then I can mend it if necessary, why not indeed.
For me it's about the fishing, not the casting. And casting beyond 60 to 70 feet is rarely required on the rivers I mentioned. The right tools for the job for my limited ability is skandi for floating and intermediate lines for flies in sizes 2-12 and Skagit for Sinking lines and fly sizes 2/0 to 6 as it applies to the SEVEN weight spey rods I own, the winston BIIx 7/8, the sage 7136 IIIe and the T&T 1307.
For the guy that asked the original question about 7/8 weight rods for scandi, my experience with the sinking scandi lines was not good. I let them go in favor of the above system for fishing west coast native steelhead in the above rivers mentioned.
To each his own of course!
