In terms of throwing consistent winners, the chula probably
has to rank right up there for the vast majority of players. You
need power and perfect form to even have a chance to throw one.
You also need some incredible aim and probably a little luck.
Think of it this way, with a little math. If a player throws a backhand return from the 12 line and tries to throw a chula they have to throw the pelota a total of 330 feet just to get it to the back wall. That's 110 yards and longer than a football field. Now imagine throwing a ball that far accurately, then imagine doing so with a bounce off of the front wall.
Doesn't sound very easy, especially considering the pelota has to hit the back wall within an inch or two of the floor to guarantee a chula winner. In fact, the chula may rank right up there with a long chip in in the sport of golf in terms of difficulty.
