Tom,
Any chance you are thinking of Suffix Seige? That is their line similar to the old XT lines by Trilene. It is more abraision resistant. Elite is quite a bit more manageable like Trilene. In my pea sized brain, you will not find a stonger more manageable line than the Suffix Elite. No, I am not sponsored by them either.
I like the way Elite goes through slip bobbers, and I like the hookset power when dragging Rigs.
Both lines are high quality, and you cannot go wrong with either. I think the differences may be so inconsequential that a normal angler may never tell the difference. (I consider myself normal! )
