Please can Photoshop update the Pen Tool, so instead of just being able to draw shapes with a line, you can select some of Kyles Brushes. So for example you can use the curvature pen tool and a soft pencil brush to draw some lovely clean shapes with a pencil edge. :)
You can currently select a brush, draw a path, then stroke the path using the Paths panel, but it's not nearly as flexible as Illustrator's Art, Scatter etc. brushes, where you can edit the path after. I'll vote for them enhancing the feature.
But in the meantime, if you haven't tried out the Stroke Path feature, give it a go. It does work with Kyle's brushes. Just be sure you select the brush and the brush size before you stroke the path since it only lays down pixels.
