Just for information : 
- about www.google.com & www.google.fr

www.google.fr.          16h17m34s IN CNAME  www.google.com.
www.google.com.         3d16h17m34s IN CNAME  www.l.google.com.
www.l.google.com.       5M IN A
www.l.google.com.       5M IN A

Google use a round robin of 5 minutes.

- about max connection to DNS servers.
Our B2C DNS structure receive (depend of hours) from 6000 to 9000 connections per second

- regarding Load Balancing.
As for me the best way is to use load balancing even if it's software load balancing...You're going toward problems using such a low TTL level
