The current at Blue Corner can be strong but it depends on the time of day. I've done solo dives there with absolutly no current.
Sam's sells reef hooks with handles for safety reasons and they are not hard to hold on to even in a heavy current, although I always hook mine to my BC because I'm taking photos. Divers not experienced in using lines attached to them in current should start out with one that has a handle.
There is a large area right at Blue Corner that has plenty of hook in areas as it is live coral free and as you mention, lots of hook in points.
Not to nit pick but that thread was started in 2003 so it was a while ago. (Just so no one starts a thread ...
)
