You shouldn't really need a trap or alot of tranq they are pretty hard to miss head shot or miss and if you have bumped your movement a little you can easily out run a wild rex get distance fire a few tranq run shoot etc... it's torpor is so slow even if you leave for a few minutes to make a new bow or narc. It shouldn't matter at all super easy and able to do on foot by the time you can make tranq arrows
