Recent data on ${K_L}^{ 0}p\to {K_S}^{ 0}p$ are interpreted in terms of two distinctly different Regge models, both of which provide good descriptions of the data. The forward differential cross sections for ${K_L}^{ 0}p\to {K_S}^{ 0}p$ and ${\pi }^{-}p\to {\pi }^{-}p\to {\pi }^{0}n$ are used to determine an $\frac{f}{d}$ ratio for the nonflip coupling of vector mesons to baryons.
