An attempt is made to fit certain data for the reactions $K^{\pm }p\to K^{*}\mathrm{}\left(890\right)\mathrm{}{\pi }^{\pm }p$ and ${\pi }^{\pm }p\to {\rho }^{\pm }p$ using simple Regge models incorporating the Reggeon-particle spin couplings of Blankenbecler and Sugar. The aim is to see if a universal form of such spin couplings exists. It is shown that this is not the case if simple, unadorned Regge models are used, but that if absorption is appealed to virtually any type of spin coupling will yield successful fits to existing data.
