Well, Burma was more than just a flood, and is a long term kit. For a larger stock, yes, having more tackle and line makes sense, but a gill net is your best bet.
For a small kit, the biggest purpose of a fishing kit... *looks around* C'mere... *motions firefly closer* Don't tell anyone, but *whispers* in a PSK, the biggest role of a fishing kit is to keep you out of trouble and near a clear spot where air search can find you in the first three days.
For that role, little hooks and 8 pound mono line is fine. Besides, you are more likely to get <3 pound fish. You KNOW those are in any healthy pond or stream. I stick a
tiny fishing module in small kits, along with about 30' of 12# braided specta, which is similar in thickness to 8# mono and doesn't have the memory. That's enough to get out a few set poles, or rig a trotline with assistance of a sapling or a bit of paracord. To give you some scale, that prototype is with a 2x2" ziplock.
