I Just finished going over to the Dynasty Blog and watched a couple of their U-Tube Videos that you can "get to" from their blog. Go to: http://www.dynastybrush.com and in the menu at the left choose their Blogsite.
They have some great information, tutorials, videos etc. on both sites that are worth your time watching.
IMHO Dynasty brushes are the highest quality brushes and best performing brushes I have ever used.
There are many "types" to choose from. I love the Dynasty IPC brushes, Faux Squirrel, Eye of the Tiger, Dynasty Decorator Series, and the Micron mini line. It all depends on what I am painting and my surface which of these brushes I will choose to use. AWESOME brushes.
