The nation's best wrestlers compete for national titles and All-American honors at this outstanding showcase event.    The Men's FILA Junior National Championships feature the nation's most talented athletes who are 17-20 years old, and includes both freestyle and Greco-Roman.     The Western Junior Regionals features the top high school wrestlers in the region and the nation, competing in freestyle and Greco-Roman. This is annually the largest of the Junior Regional events and features a very strong field of competitors.    Mandatory online pre-registration was developed in order to make registration and participation in these events more efficient for all the participants. It will also allow the national championships to be runin a more professional and convenient way.    "It will streamline the system," said Event Director Larry Barnson of the Las Vegas Sports Committee. "It will make it easier for athletes, coaches and event organizers. It will be a better experience for all involved."    With the new online pre-registration, credit card payments for entry fees will be accepted for the first time for the U.S. National Championships.    Those individuals not comfortable paying with a credit card can mail in their entry. A $10 service fee will be applied for all mailed entries.    In addition to pre-registering the athletes online, there is also a process for coaches to pre-register their team rosters on the web page.
