I read this post, and ordered a few of the 'swizzle sticks'. My review is a little mixed, but I took some photos to show.
I believe they helped, but not as dramatically as I had hoped. First, my setup is 5' of 3/16 bev line, temp 40*F (or colder), 15 psi. I have two on tap for about two weeks now, and they are/were pretty foamy. I poured them into small glasses to make the foam more noticeable.
All pours had a 'line clearing' pour first to prevent line foam affecting the pour. Forward seal faucets.
First pour ALE no swizzle sticks:

Here's a pic of the swizzle before going in:
Here's a another just for fun:
Here's a full beer pour with the large 18-20 ounce glass:
So, hopefully these pics help you all out. Just for those who want to know I wick the throttle open and closed to prevent foam. I can't think of anything else to help the foam, save turning down the pressure. Granted most probably don't carb up to 15 lbs, but for the ale's I like it, for the browns I like a little less.
