As an update to my earlier post on Trout Spey rod. Here is George Cook himself introducing the Sage ONE 2 wt (10'9") and 3 wt (11ft) trout Spey, new for 2015. He also talks about the various RIO lines that will be suitable for this rod including the new 11' Skagit Trout Max line.
He made a very good intro to the Skagit Trout Max explaining why the line is designed so short...mainly for streamer fishing for Trout where it is necessary to strip the line in close without hitting the loop to loop connection.
