What weapon to use for spectral shield throw?

Advancing fortress for 15% block
Ornament of the east for "hits can't be evaded" (does it work with SST?)
Ewar's mirage for +1 chain
Relentless fury for culling strike + onslaught (does it work for SST?)
Prismatic Eclipse for 36% aspd
Beltimber blade for far shot + 2 extra projectiles

Thoughts?
