The warp factor is determined numerically and subsequently used to calculate cosmological observables including the scalar and tensor spectral indices, for a sample point in the parameter space. As one moves away from the KS solution for the throat the warp factor is qualitatively different, which leads to a significant change for the observables, but also generically increases the non-Gaussianity of the models. We argue that the different models can potentially be differentiated by current and future experiments.17 pages, 10 figures; v2: section 4 expanded, references added; v3: typos fixedHigh Energy Physics - TheoryAstrophysicsHigh Energy Physics - Phenomenologytext
