Very nice looking job on those rod holders Andrew, do you have one on each side?
I have done the leg hold thing, and it does work, but it does not allow you much freedom of movement while paddling. Another good thing about a rod holder is it is a great place to put your rod, even if not fishing, rather than risk it getting caught up with gear, dog or bow paddler.
I have tried them on the gunwales, but they need to be switched to the other side when you change sides to paddle, but mounted center on the thwart in front of you allows you to paddle either side, no matter what side the rod is on. I do always tend to move it to the off paddling side though.
I am on my second clamp mount, the first being a plastic on similar to the Scotty offerings, but the mount cracked and I went for another brand, Tite-lok. It is made of aluminum, is very light, tough, and works great. I have only used it once to be honest, but am really impressed with the build, I expect I will have it a long, long time.
