I'd rather have another shot at the $10k, myself. You know, there is something to be said for the lights, the pressure, the money, that hundreds of people are watching. I don't mind people getting a second chance to do it right, but I agree, I didn't think that you could go from $500 in the first half to $25,000 in the second.
Side note: if you DID conquer the Pyramid on your second try (in the 80s, did you still just win the $25k, and not the token money for each box in the first half too?
