We've gone with static /56 v6 ranges for customers.   Why?  Customers told us they wanted address stability.   Pretty 
much more than anything else.   Admittedly the people who opt'ed into the trial part are not typical customers, but 
it's something they were all fairly adamant about.

We're small globally, but we're the 5th largest broadband provider in Australia and we've actually gone and delivered 
IPv6 natively to our broadband customer base (as well as corporate and other clients).  We also sell only v6 capable 
ADSL CPE (ie. have actual firmware that works with dual stack broadband.
