One of my problems is that I'm so inconsistent.  One hit I'll knock off a whole bunch of it.  The next one won't go near as far and leaves a bunch of coretex in the middle.  Then when I finally get a good platform, I botch the flake and step it or crush it.  Pretty soon I have an island like that.  I'll get it, just need more  experience.  Thanks for the help.
