when you paddle upwind to a barrier on rising tide, stake out and wade for fish sign, then put out the drift sock to bind fish home sitting in your kayak seat, the longer the rod, the better. This is for keeping better control on your lure depth fishing grass with long blind casts while sitting down.
For my baitcaster, I use a Lamiglas Rogue River Special, 8-1/2' 10-25-lb, 3/8-2oz.
My favorite spinning rod is a Lami G1325 Medium Light, 9' 6-12-lb, 1/8-1/2 oz.
Both are NW steelhead rods, but perfect for this task.
I also have an 8-1/2' Loomis G2 spinning rod, rated the same as the Lami Rogue River, but it's more work to fish than either Lami graphite.
My inshore fly rods are Sage RPLX7 and a Japanese inshore S-glass rod, 8-1/2' 6/7-wt para taper, which is a jewel. It does everything the RPLX does with less fatigue, unless the wind is over 15 knots, then only the Sage works.
