Thanks again, both you guys. It would seem you are indeed the Guru's of the sharpening universe. I will be looking on line for a new software plug-in, one that I always suspected would work (back in my old 8mp 20D days). It is interesting Noel that I have been playing around with a similar tactic of decreasing radius passes with unsharp mask. I guess I wasn't entirely barking up the wrong tree. I'm not sure why multiple passes seems to work so well - but it does. Would it be partly because you are averaging down % wise on each pass rather than taking one big chuck off the original. I guess you could look at like moving down in sandpaper grades to get to the final finish.
