IS-IS has no reference-bandwidth concept, but as with you, we've also used a 1Tbps base, considering multipliers based on whether links are national or international as well (you don't want local traffic switching between two different countries that have a very low latency between one another). The challenge I had with a 1Tbps base was when links were very small (for IS-IS, you can easily exceed the actual metric value). But with the smallest backbone links now sitting at about 10Gbps, it's not a major drama.
