The Saronite Plated Legguards may provide less avoidance (about .05), less threat, and 2.8 less defense but the fact of the matter is that the 800 armor is much more EH then the T8.25 pants. When looking at getting max EH prehard mode that 800 armor makes it the better choice. Unless you are focusing on threat instead of survivability.
Thank you very much for your quick reply. I will take that into consideration then and switch for further hard hitting bosses.
