pigeonhunter,
Sounds like that was just a bad presentation. I hate when someone sets one where you can't see the clay, and I hate to see very short window shots.
One club I went to, had a clay that came at you up hill at a slight angle, and the clay was tilted so that it would curve to the right. It was not fast, and looked to be a easy shot, but I missed several. I thank the hill played tricks on the eyes.
