i've never been to pakistan but I would say a good old fashioned wooly bugger or clouser minnow would work anywhere in the world. the basic attractor nymphs like a hares ear or pheasent tail should also work? ask him what kind of bugs fly around and to go from there. are there mayflies? moths, dragonflies, even a regular housefly could work? anything that he sees around that be used as top water? bees? ants? crickets, hoppers, scorpions? I am thinking it might be desert like there? I have no clue.
