Hey guys/gals, I'd like to get into a tablet for sketching as I find I churn through paper and use a lot from doing revisions of sketches. I sketch building designs - plans, elevations, perspectives - typically black and white 'sketchy' drawings for quick communication and testing of ideas. Nothing overly 'artistic' perse, but I like the sketchy look. Any suggestions for what hardware to look at? iPad pro is what most people say, but they're super exy.. I have an old iPad Air but I figure something slightly bigger would be better.
