Big fan of the sketches-only approach for those reasons, but more for getting the "client" to engage on usability and functionality before trying to nail look.

Big fan of the sketches-only approach for those reasons, but more for getting the "client" to engage on usability and functionality before trying to nail look. Hard to find fully convincing sketch only tools, but do have a decent set of sketch style templates and stencils for Omni Graffle on MacOS (such as Konigi's sketch stencils: https://konigi.com/blog/omnigraffle-sketch-stencils-now-available/ https://konigi.com/blog/omnigraffle-sketch-stencils-now-avai... ) along with a subset of not-quite-architectural handwriting fonts. With sketches the feedback from users, managers, stakeholders, and clients, is much more substantive and on track for iterating usability and flow. // Flow feel requires clickable sketches, think Balsamiq at https://balsamiq.com/wireframes/ https://balsamiq.com/wireframes/, but sketchier.
