there's a Tony Ryder book that talks about the blocking in method for figure drawing that's been
conducive to speed and accuracy... Of course, some days go better than others. The Classical Drawing Atelier book by Aristides has also been very informative in this respect. These are straight ink, but I use the pens because I can ghost in the lines and pound in the ones I like.
Ink no smear, me like for that reason.
These books are my self imposed correspondence classes. Always on the lookout for great artbooks!
