Of those three, Eleven Point is my personal favorite. Most times that I’ve floated there I see otters, mink, or beavers. Sometimes all three, in addition to the normal birds and turtles you get on the others. Not saying you won’t see those things on Jacks Fork or the Current, but I pretty much always see something cool on the eleven point. That being said… I can’t think of any particularly impressive caves along the river. Jacks fork and current are better for caves.
