i think that choice band should be the main / only set. focus sash is just garbage. it can't trap anything really. roserade, nidos, victini, heracross, mienshao, jirachi, the list goes on. sash dugtrio will end up doing 75% to a ground weak pokemon and then dying. i used dugtrio a LOT, and i can't begin to tell you the usefulness of choice band -- between actually OHKOing the aforementioned threats and picking off a ridiculous amount of stuff at low health (even trapping a knocked off florges) is sooooo useful. sash is just a bad set
