The increasing accuracy of experimental results for the exclusive, semileptonic decay B → πlν requires a similarly accurate calculation of the hadronic matrix elements, to determine |Vub|. We present preliminary results for the form factors of the B to light meson decay mode. Using results from three lattices in the range 5.7 ≤ β ≤ 6.1 we study the dependence on the lattice spacing.
