I have tried Stubby's twice on Canyon and not even a nibble.
I attributed it to all the new water messing the fish up. Or maybe I'm not doing something right. I would love to get on some cats here soon. Was he fishing off the bank or boat? I was in my kayak so it was hard enough keeping in one spot.
I'm a yakker also. If you are having a hard time keeping in one spot, it sounds like you don't have any kind of anchoring. I wouldn't even get on the water without an anchor and anchor trolley.
You just have to find the fish. Finding fish beats bait and presentation every time. If you aren't catching fish in 30 min (or less!), move! Also, if you don't have half a day to put into it, don't worry about getting skunked. Sometimes you just run out of time finding the fish if you only have a couple of hours to fish. Happens to me. I'm lucky to get a couple of hours on the water frequently, so I can handle getting little to no action some days since I'll be back out for another short trip soon. You are in a kayak which will allow you to cover a lot of water, but your range IS limited. Some days just aren't going to work out.
