Minimum IPv6 allocation to ISPs is /32 which will allow you to
assign /48 prefixes to broadband customers.

This makes network design simple and you would be following
the same mainstream IPv6 implementation rules as most
other ISPs. This will make it much easier for you to get support
from your vendors and advice from other ISPs who are
deploying IPv6.

It also prevents your competitors from telling your customers that
your service is bad because you give customers a smaller block
of addresses/subnets.

Really, only mobile phones or other devices should get /128 prefixes.
Anything that is a network with potentially two or more devices on it
should get a /64. And a broadband customer is a "site" so they should
get a whole /48 unless you are very big. Some very big ISPs are
giving /56 to customers in their private homes and only give /48 to
an office or some kind of business.
