We demonstrate how both normal and anomalous dispersion can be realized concurrently for a pair of weak probes in a doubly driven double-ladder configuration with independent and simultaneous control for group velocities of the pair. We have shown both analytically and numerically that, because of electromagnetically induced transparency and a ${\chi }^{(3)}$ -based gain process, a slow-fast light pair can be realized in the same delay element with group indices $\sim \pm {10}^7$ accompanied by gain or relatively small absorption (down to $\sim 25\%$ ). We also identify parameter regions for realization of concurrent slow-slow and fast-fast light pairs with reduced absorptions.
