I have to admit that I am not at all loving this provisional cast on. When I made my toe up socks, I just used my long-tail cast on and pick up stitches from the other side and that seemed work well for me.
Youtube is one of the best resources to look for examples of provisional cast on. I wish you the best of luck finding what you are looking for.
Here are some of the provisional cast on videos I found that look interesting;
