DK 2011 Sentry vs. Intense 2010 Race Pro Bike
 

I've got a 5'6" son who is looking for his first BMX race bike. He's not a novice rider, but he is a beginner when it comes to BMX racing. We are considering the DK 2011 Sentry or the Intense 2010 Race Pro Bike.

Thoughts on which would be a better fit for my son? Many thanks for your comments and recommendations.
