Lausanne has 3-4 huge lineman and multiple fast players. I think they are unbeatable. ECS looks pretty big too but not as fast. It appears one of CPA's strengths is strategic holding at the line. They don't generally take defensive players down, but they hold on almost every play and it's never called. Of course, the game I saw was at home. Like you say, a tight zebra crew might hold them in check as well.
