Should a volleyball player play up an age group in club volleyball?

Say there is a very good high school junior who normally would be on a 17's club team, but has been asked to be on an 18's team. Should this volleyball player play up an age group for her club volleyball season?

The pro's of playing up:

• Better competition; all in all, a high school senior is better than a high school junior.
• More prestige.
  
• Possibly more expoure to college coaches. If you are playing in a 17/18's bracket, your 18's team might rank higher than most 17's teams and higher ranked teams generally have college coaches stay longer to watch.

The con's of playing up:

• If you don't play much college coaches can't see you. Even though you might start on many 17's teams, if you don't play, it is hard to get noticed.
• You miss a year of bonding with players your own age.
• If your 17's team isn't very good you might not get college coaches watching.

Ech situation is different, but in general, it is not only important to receive high quality coaching during competitive practices, it is important to be seen at tournaments if you have college aspirations.
