Default LM4702 - BJT recommends (non-Darlingtons) for amp

Hi, working with the LM4702 some. I don't want to use darlingtons like National uses but discrete BJTs and add my own discrete driver of the main outputs. Does anyone have some favorite BTJ parts for use with this chip? I was thinking of using the BD139/BD140 pair as drivers but not sure if these are a good choice or if I should use the TIP31A xsistor that National uses as their Vbe multiplier. Thanks for any input, still pretty new to discrete amps.
