Fifa 2010 Ball Jabulani

FIFA World Cup 2010 BALL?
I have seen the Jabulani ball and it looks amazing. I also heard that the ball is lighter and flies faster through the air. Because the ball is far to much money to spend on a everyday use soccer ball, my question is this. On Sportsauthority.com they sell the official replica ball and something called a glider ball? I know these balls arent the same as the match ball, but will they both be lighter and fly faster through the air? Also for future refrence, what is a glider ball?
Thank You
I highly doubt that it will be lighter or fly faster than a normal ball.
Basically its just the name given to a series of balls being made by adidas, it costs less to buy but costs less to make, it uses cheaper materials and easier construction methods. It is considered a ball for practicing with, which should hold up well but is not considered match quality.
