All good suggestions. If your going to spend a considerable amount of time in the Yak and fish the Rock, I would add a fish finder. Nothing fancy or very expensive, just a basic compact unit. Fishing TR without a fish finder is like fishing with a blind fold on, a must have IMO. Another suggestion on where to get kayak gear is Ozark Mountain Trading Company. They have two locations, one in Garfield, Ar and the other in Ozark, MO. I have traded with them for the past 5 years, Bruce and Larry Jenkins are the owners and they will take good care of any needs you may have. They carry a good stock of fishing accessories as well as everything else needed.
The wife and I enjoy going out in our kayaks mostly on the upper Kings, Buffalo and War Eagle.
