Good balanced review. I personally found the sag to be well within acceptable bounds and really enjoyed her soft natural feel - a nice change up from the usual implants. And I say that as someone who loves big enhanced girls. I agree it's a stretch to call her pretty, but I found her pleasant, and I'd rate her face ahead of Michelle if I'm honest. Also found our personal physical chemistry to be way up there - it just felt natural being body to body with her. But that's a totally ymmv thing.
Now that you mention it, the tobacco smell was a bit of a turn off though.
