I am a little hesitant to jump into this discussion, because there are others a lot more knowledgeable on this topic than I am.
I also want to say that I really haven't had time to look at the links provided. Therefore I am not completely sure if what I am about to say is valid to this discussion.
However, based on what has been discussed so far on this thread, it would seem to me that this is more about an inside debate between 5 point Calvinists that has been happening for centuries now.
Most of the time when I see this debate happening between 5 pointers, it usually has something to do with how one should interpret John 3:16.
Or it has to do with common grace and what is actually provided by common grace.
I have been on the Highway for quite a few years now and these two things have been discussed a few times that I am aware of and probably quite a few more.
All 5 pointers believe in limited atonement, but some (Spurgeon among them) believe that John 3:16 is talking about a general love for all mankind. However even they wouldn't go as far as to say this love was effectual for all mankind. They would say effectual love is only for God's elect. Hence many have said that the death of Christ is sufficient for all, but efficient only for the elect.

Of course this argument is rejected by many (most on this board) in favor of saying that the word “world” in John 3:16 in context is talking about specific people from all over the world. They say this because the context of John 3:16 is specifically talking about salvation.
All this to say that I don’t believe this has anything to do with historic Amyralianism, who believe in 4 of the 5 points.
