The best method for fishing a Senko, according to the video context, is to cast it out, engage the reel, and let it sink. The Senko is a soft plastic stick bait that flutters, moves, and wiggles as it falls. While it's sinking, it's important to watch the bait and the line for any twitches, jumps, or odd movements, as these could indicate that a fish has grabbed it. Once the Senko hits the bottom, you can lift it up with your rod tip and let it fall again with slack line. Reel up some of the slack until you almost have the bait, but avoid moving the bait with your reel.

Another method mentioned in the video is to twitch the Senko back to the boat after casting it out. You can do this at any speed, from slow to fast, and it can mimic a jerk bait or a baitfish skimming across the surface. This method is particularly effective when the fish are feeding on schooling baitfish.

Additionally, you can drag the Senko on the bottom to imitate a baitfish like a sculpin. To do this, move the rod tip to the side and reel up the slack as you drag the bait along. This method can be successful when trying to target fish feeding off the bottom.

It's important to pay close attention to the line and any movements or jumps, as bites often occur on the fall or with a slack line. Setting the hook at the right moment is crucial to avoid gut hooking the fish.

Overall, the best method for fishing a Senko is to experiment with different techniques, such as letting it sink, twitching it, or dragging it, and see what works best in your fishing conditions. Remember to pay attention to the line and be patient, as sometimes the bites can be subtle.
