The residential currently eats up a majority of my addresses, so the 
more I can recover from them for business customers, the better.

Perhaps my viewpoint is different, given that I only have two lines of 
support folk, and talking to me is a rarity for a customer. :)

That problem was mentioned on v6ops, and the general lesson that I took 
from it is to not exceed 16:1 ratio if it can be helped. 4k ports should 
be fine. 64:1 is probably sustainable for a lot of customers with 1k 
ports, but there will be a percentage that will have issues. Luckily, 
most of those with issues are usually running services that require 
opt-out anyways.

If I calculate correctly, even at 20% of my residential(70% of total 
allocated) on CGN, I'm regaining 18% of my residential assignments with 
a 16:1 ratio. I could conservatively figure a years worth of my usual 
allocation has been saved. If I can push better numbers, I'll get more 
years.
