Recent precise measurements of sin2\ensuremathβ from the B factories (BABAR and BELLE) and a better known strange quark mass from lattice QCD make precision tests of predictive texture models possible. The models tested include those hierarchical N-zero textures classified by Ramond, Roberts, and Ross, as well as any other hierarchical matrix Ans"atze with nonzero 12=21 and vanishing 11 and 13 elements. We calculate the maximally allowed value for sin2\ensuremathβ in these models and show that all the aforementioned models with vanishing 11 and 13 elements are ruled out at the 3\ensuremathσ level. While at present sin2\ensuremathβ and |Vub/Vcb| are equally good for testing N-zero texture models, in the near future the former will surpass the latter in constraining power.
