Well, if it were fixed price you'd eat that discovery, correct? T&M doesn't stop you from not billing for something. Again, the question was: There are too many unknowns. The answer is T&M. Btw, they can be combined. Fixed price on the knowns, and T&M on the unknowns. Put it this way, I've seen 5x more fixed price projects go sideways than T&M. That's how bespoke work works best.
