To include/exclude a fishing kit seems to be one of those perennial debate's. If your simply stuck overnight then no. If it looks like you have to self rescue then yes, most definitely. In that case 40' of line and 20 hooks seems to be advocated by most experts. Along with a couple of jigs.

The line should (preferably) be a braided one, like Spyderwire. Hooks have other uses beyond catching fish. Like catching small game such as birds or lizards. Line can be triggering trap's etc.
So personally? Yes I would include it.
