I converted the original Lucida Grande fonts from Snow Leopard to ttf for Windows compatibility. I don't know if I could upload these here but just in case.
Original Lucida Grande have a great spacing and proportions compared to Lucida Sans or Grande that comes with Windows.
Hope you like it
ps. Remeber to use Mactype for font smoothing (I suggest to use registry hack settings). Google for Decency ini config, looks great.
