i think rota slipstreams are decent, seems like their everywhere i go. but their real good rims since their so light and affordable. not sure how strong they are, but their made in the PI and their cheap, cant expect quality rims. depends on what abuse its taking, cant be hopping corners and doing crazy stunts. the weight shouldnt matter of its quality, its more of the material used of the rim. i forgot what material rotas used, but i think something like cast aluminum ?
