So, I have been looking at march numbers and stuff again this morning. It is easier than ever to cap Magic Haste (Embrava, two good marches + Haste, etc.), so that's what I'm aiming this set at
.2 = (1-DW)*(1-Haste%)
.2 = (1-.3)*(1-.433-.1-X)
X = .18
So we really only need about 18% Haste and no Dual Wield in a delay-cap build. The main question is what we swap in/out.
Dagger/Dagger/____/Potestas
AF3+2/Rancor/Ghillie+1/Brutal
Thaumas/Miodio/Epona's/Rajas
Atheling/Twilight/AF2+2/AF3+2
29% Haste, only need 18%.
AF3+2 feet -> Thaumas (STR+2, DEX+1, DA+3%, STP-8, Atk+15) :: down to 25%.
Twilight -> Anguinus? (DA-1%, Acc/Atk+15) :: Down to 18%
