Photoshop Brushes

When I was making a new brush in Photoshop I discovered that holding Alt and clicking on one of your presets irrevocably deletes it. So while I was figuring out what brush I deleted and remaking it I decided to prune my brushes down to what I'm currently using. The first two at the top are what I use about 97% of the time, with the opacity at 10-50% and flow always at 100%. I'll e-mail my .abr file to anyway who wants it, either this or my non-pruned file with spider web and bone pile brushes.
