The Intuos 3 is great! I´ve never tried any other tip other than the standard/default one. It seems to work fine. As far as setting up a profile to work with ArtRage, I never did anything other than install the tablet and start painting.
(One thing that has happened to me a few times: the zoom feature starts going crazy and moves from 0 to 800 and back without touching anything. That makes it impossible to use AR, and generally any other program. If that happens, unplug your tablet, go to the Wacom site and download and install the latest driver. Plug the tablet back in and do a restart. It always fixes the problem.)
The only problem with humor is that no one takes it seriously.
