Interesting experiment, and thanks for taking the time and effort doing this sort of thing, Alan . I think hese kind of experiments can be useful 'cos they come from the opposite direction we usually take. We're all naturally consumed with getting our razors sharp (and the right kind of sharp to boot), but I guess it's also a good idea to sometimes experiment with achieving the opposite results so one can have a more intuitive understanding of how the material behaves - ya know, the whole gestalt.
