Runes for Yasuo post 5.1?

I've been playing Yasuo and really enjoying it, especially the skill cap since I used to play Annie a lot ;)
With the recent changes to IE, reducing its crit. chance by 5%, it means my full build (with Static Shiv + IE) only gives me 80% crit. chance.
It used to be 90%. I would use a 4 crit. chance red runes and 1 crit. chance yellow rune to make it 100% late game. Now with this change, do you think it is viable to still go for 100% crit. chance? That means I would need more crit. chance red runes, sacrificing some flat AD or attack speed. Or I just go completely without crit. chance runes and accept that my crit. chance will only get to 80%?
