I thought I'd share my tool presets. I've been using the Tools presets almost exclusively now and I got to say that I like having a brush set up exactly how I want it.
About the Tools. While it might say something like "Wicked Leaves" you should know that you can use it for whatever you want to randomize, alter color, and scatter. So you'll have to play around with them to get use to them.
Anyway, I'm not sure this will work because I'm not sure how photoshop stores them so let me know if they work for you.
1. Unzip into your \Adobe Photoshop CS6\Presets\Tools folder. Mine exists in \AppData\Roaming\Adobe\Adobe Photoshop CS6\Presets\Tools
2. Select Window > Tool Presets and arrange where you want them in your workspace.
NOTE: Some brushes might have been submitted by other sets. They deserve the credit, but I don't remember when I got them.
