Pendulum restrictions were removed from the 2013-14 rules, making many more pendulum style transitions legal than in the past. You still need to be conscious of landing inverted and passing through an illegal stunt (such as passing above a prep level 2 leg stunt in Level 1 or passing above prep level as a 1 leg stunt in Level 2), but there is no longer a required number of catchers or the overthrow catcher.
