Hi, I'm currently using the Sage ONE 8136-4 and love the casting action, but air-line travel with a 4-piece spey is inconvenient to say the least. Does anyone have experience with the 6-piece 7136-6 or the 9140-6 ? Are the casting action similar to the 4-piece? I need to take an international flight to any salmon/steelhead waters and the ability to bring the rod on board as a carry on is a big plus. Thanks in advance.
