[Ifeffit] Question about k-weighting real-world practice and outcomes

Dear EXAFS folk, I'm a graduate student in Jerry Seidler's group at the University of Washington, Seattle. I've been doing a numerical and experimental study on how to optimize k-weighting for EXAFS when the total experimental measurement time for a study is constrained, i.e., when you have 1 hour at some given I0 flux and your job is to get the best results, in terms of best fits or cleanest g(R). Can anyone aim me at 'famous' papers (or at least 'standard' papers) on the best use of k-weighting? Also, it would be great if people could informally email me how they, personally, do k-weighting and what their personal experience has been. My email is jbferre@uw.edu. Much appreciated! John
