I use hg-git with our 9GB company repo. Be warned that you will need quite a bit more disk space for large repos especially if they use a lot renames. My hg copy of our company repo which includes the entire .hg and .git folders along with the working copy is 33GB. However, it’s completely worth it. At this size, mercurial is a little slower than git, but not enough to care.

$ du -sh .git .hg .
9.3G	.git
 20G	.hg
 33G	.

The only thing I would add is to be a little careful with modifying history (e.g. commit —amend, strip). Then, you might need “hg git-cleanup”, “hg gimport”, and/or “hg gexport”. I’ve never gotten myself into a mess that I couldn’t fix.
