If you want to ping your customers you should probably use a /126 so they can only use the specific address you give them. You need that anyway if you want to route a /48 or what have you to them.
Having just done an IPv6 rollout, I went for a block of addresses which I would use just for p2p links, split it into chunks for peers, customers etc, then used a /126 for each link. Seems to work fine and (I think) seems to be what most people are doing.
BTW, there is discussion about rethinking /48s for customers in IPv6. Thoughts?
The current recommendation for a /48 for any customer (pretty much) does initially seem to me to be a bit wasteful, though that's perhaps because I keep thinking in IPv4 terms. Having said that, I think that perhaps a /48 for home users isn't _really_ necessary.
