Sorry, I guess I should have said like to use Colibri as an approximation for other events like Nyzul, Assaults, Limbus, Sea/Sky farm, etc.
Since you don't have Usu feet (which isn't common, so don't feel too bad =P) with 5/5 STP merits, Rajas Ring and Brutal Earring full time; you should TP in Hachi hands/fuma and WS in Alkys(or Pallas)/hachi feet. Like Baja said, there's a lot better hands to WS in than feet. You could also TP in Dusk gloves/Hachi feet but that costs more and you also have to deal with movement down, that's why Hachi feet/Fuma is the normal.
You can replace Hachi feet on WS with Askar body, but there really isn't anything better to WS in feet to merit that switch. I would recommend against it and just WS in Osode (or Haub if you don't have one)
EDIT: While I just noticed you don't have Brutal Earring, this does not mean you don't have a 6hit. Since you TP in Hachi Hands, there's a surplus of STP on it to cover the loss of Brutal Earring's 1 STP. On WS, you also have AF+1 legs, which cover Brutal Earring's 1 STP and allow you to use Hachi feet to still maintain a 6hit. If you are looking to increase your damage output, Byrnie +1 isn't the way to go, I would suggest Brutal Earring and/or Byakko's Haidate to be next on your list.
