The '97 version has instances of overcooked bass as well, but in different places. I pretty much went with whichever blended best into the overall soundtrack, and adjusted the levels for each bass effect that needed changing individually.
R2's fall ended up being a 12 db reduction of the '04 effect, providing just a tiny amount of oomph rather than a needlessly massive impact. Strictly speaking, it doesn't have to be there at all, but I like the way it sounds. ;)
