putting an IWC choice as #2 is essentially the kiss of death, for the longest time if you didn't put an IWC designator as #1 you weren't going to get selected. Supply is pretty much the same thing. IWC and Supply have very low selection rates, sometimes as low or lower than 10% while SWO can be much higher.
And now SWO seems to even want being the #1 choice to get picked! I guess put whatever you want most as #1 and cross your fingers, knock on wood, and stand on one leg to even get considered for your #2 choice.
