The existing data on the line-reversed reactions ..pi../sup +/p ..-->.. K/sup +/..sigma../sup +/ and K/sup -/p ..-->.. ..pi../sup -/..sigma../sup +/ near 4, 7, and 11.5 GeV/c are discussed from the point of view of weak exchange degeneracy (WEXD). It is noted that a smooth and simple generalization of the model of Navelet and Stevens is able to describe adequately, in the Regge region, the data at 7 and 11.5 GeV/c. (Recall that the Navelet and Stevens model appears to fit the pronounced violation of WEXD for leading K/sup asterisk/ and K/sup asteriskasterisk/ exchanges in the data near 4 GeV/c whereas the data at 7 and 11.5 GeV/c are in agreement with this particular WEXD.) A prediction for 70 GeV/c (namely, essentially that WEXD for leading K/sup asterisk/ and K/sup asteriskasterisk/ exchanges should hold true) is given. Further, an effort is made to indicate how this particular generalization of the model of Navelet and Stevens may arise in a dual multiperipheral bootstrap model of the general Lee-Veneziano-Chan-Paton variety as formulated by Balazs.
