Best tournament sites?

Which US poker web sites are best for NLHE tournament players?

I enjoy big tournaments with slow structure (10 min or longer levels) and wide range of stakes (opportunity for growth). In particular, I really like the tournaments at Carbon but have been seeing negative comments about the site's future.

Any other recommendations?

I like Americas card room only annoying thing is super long late reg some times but overall a great fun site to play
