The thing to remember about winding sticks is that they are dead simple. 2 boards with parallel edges is all that is required. They don't even need to match in height.
I have a 18" set I made from walnut with maple inlay on the corners of the rear stick. The maple makes it super easy to see. 18" is a good fit for me because my bench is small and up against the wall. For 6"-8" wide stock, they're perfect but they are a little short for wider stock. I have a 24" set on my to-do list.
I'm not sure how I got along without winding sticks.
