I briefly tried a few lines that I have already in hand on a new to my Z-Axis 7136-4. A few of them worked decently with my lack of skill while others were clearly not the right ticket. I contacted Sage and they recommended a Rio AFS 550 with a 2 1/2' cheater. I don't have that line but a skagit head in that weight did seem to load the rod well. I also don't have any cheaters, nor have I any experience using them. I plan to use this rod from the beach this summer/fall and of course will try futile flailing on some summer steelhead runs. I have no preference on long belly, mid belly, scandi, skagit or anything else for that matter. If you have a combo that works well, I'll gladly read your input. Thank you in advance for your suggestions. When I get the time I also will hit Aaron's day on the river on a Saturday and/or All About The Fly's sessions on Sunday. I just want to have something that might be servicable for my limited skills before going there.
