Instead of start a new thread, I'll just resurrect this one as I pretty much have the exact same question.
I'm quite interested in tilt-enabled brushes as well; it's why I went with an Intuos =]
I'm setting up a brush-set of ONLY tilt-enabled brushes, and have been working on some of my own to add to it. Aside from the two mentioned, anyone have a list of other tilt-enabled brushes throughout all the available downloadable brushpacks? ... I've been working thru them all, but it's sometimes hard to tell if or how a brush is tilt-enabled without explicitly looking thru all the settings, which is a seriously tedious PITA. I'm not asking anyone to do this FOR me, just any already-known tilt-enabled brushes.
also, a question re: setting up tilt-enabled brushes. When setting the tilt-degree limits in the details-graph, I assume that means the graph is applied within the defined tilt-limits and NOT that the pen simply doesn't read outside the defined limits. I'm finding it can help a bit to not half to hold the pen nearly parallel to the tablet to get the effect I need, but I'm just not sure I'm actually using the parameters "correctly".
