Great find Regdor. You're our resident tips & tricks, and important links finder.
I'm a big fan of custom curves, and it's great to read of a few on there that I haven't heard about before. What amazed me was that, as often in life, the simplest curves worked the best. (eg. Dave's midtone boost, Fotogenic's EV3). Which is probably a testament to how good the original normal tone curve is, just in need of a slight raise in mid-tone exposures.
