quick help needed

I did an idiotic thing and realised that I have just brewed (chiling now) a 21L AG IPA at about 1060 OG but only have one 12 g pack of US05. So my question is, what is the best pitching option

1 - underpitch with just one pack (Mr Malty says I need 2 packs)
2 - Go to Big W and buy some standard brewers yeast to top up.
3 - I have some 30ml vials of 1272 that is in the fridge that I would normally step up from.. I could throw a couple of those vials in but I don't know what sort of cell count that's actually adding.

Which would everyone suggest?

Pitch what you have now , get some more 05 first thing Monday .

21l of 1060... just rehydrate and pitch the one pack, you'll be fine.

I'm pretty sure the one pack will do okay.
