BD's new Express screws are really good--but not phenomenal. The previous model had some issues like a gear hanger that tended to rust, and only one carabiner hole limited your options. These weren't huge issues, but it was good BD fixed all that when they came out with the Express. What I don't like about the express is ease of placement. BD changed up the tooth angle geometry (and I believe thread pitch as well, though not sure) in an effort to aid placement. I think the old Turbo Express screws placed faster and were easier to start one-handed. Other than that, great screws.
