What is the best structure for paginating comment structures on pages to preserve the maximum SEO juice?

[HoloGuy]

You have a full webpage with a great amount of content, images & media.

This is a social blogging site where other members can leave their comments and reactions to the article.

Over time there are say 1000 comments on this page. So we set the canonical URL, and use Rel (Prev & Next) to tell the bots that the next subsequent block of 100 comments is attributed to the primary URL.

Or... We allow the newest 10 comments to exist on the primary URL, with a "see all" comments link that refers to a new URL, and that is where the rest of the comments are paginated.

Which option does the community feel would be most appropriate and would adhere to the best practices for managing this type of dynamic comment growth?

Thanks
