sorry no way that doesn't require ver7...

Adobe revamped the brush engine to give more dynamics and because of this, you can't go backwards. This means even if the brush doesn't make use of the dynamic settings ver6 won't open it.

The "workaround" is to create the brush in ver6... but to do this you need to "use" it in ver7, (select the brush, paint a spot on your blank canvas) and save the file. Open it in ver6, select the area and "define" your brush.

...anybody think of another way???
