The Firearm Blog has a post up regarding Magpul's new Angled Forward Grip. This is something that looks very interesting to me as I've never liked vertical grips on any rifle, especially an AR pattern.
If you look at the picture of me from Blackwater using the Para USA TTR, you'll notice I completely forgo the front grip and grab pretty much in the same manner (however I had to grab much closer than I prefer mostly because the forward grip was in my way).
Definitely something I'd like to try at some point. Of course, that means upgrading my handguard to something with rails.
