Well I have been using the pen for 8 years or so now and I cant draw with a block, I mean mouse it just doesn't feel natural.
It will feel odd to start with but you must stick to it and you will not go back. I think the only app I use where I need to use the brick I mean mouse is DAZ Studio, the pen seems too sensitive for it. haven't found a way to change it yet.
It is by my will alone I set my mind in motion
