No, not at hand, but to be honest,
I was really dragging my heels about about switching from organic inking to digital, even though it would save wear and tear on my wrist that's held together with metal parts.
I was still doing pencils by hand, and to be honest, it was the erasing that was kicking my butt, well, my drawing hand, until a friend had suggested that it was like switching from acoustic guitar to electric.
Just go with it. You wanna draw with your rules and regulations that you set upon yourself, or do you just wanna draw?
I don't know why I was being so cagey about it, I mean, after all, when the pencil gets scanned into the computer, it turns into pixels and vectors anyway.
