Aside from a few styles, double pedals have little use outside of annoying other band members and clearing an audience out of a room. So, if you're going to play them, I'd say at least go old school.
Your opinion is on double pedals is fine. However, "old school" double bass pedals don't exist. The original double bass pedal was a monstrosity that had a bent slave beater to allow it to strike near center and the slave itself was awful. No double bass player yearns for the days of the original DW double pedals.
The pedals Bo was referring to were all singles.
