Czech nymphing, Polish nymphing, and Spanish nymphing styles are all loosly connected to the style of nymphing Joe Humphreys is doing in his video.

The major exception with the Polish / Czech style is that you keep your line slightly off the water sweeping the tip along with the line at about the same speed as the bubbles. If you see "any" tick of the line you set the hook.

The Polish / Czech styles were created to fish for European grayling which take the fly very quickly and very lightly in fast water. However the method is very effective for trout on free stone rivers where the current is fast and deep.
