Okay, I'm in this same boat, and not sure what I should do.
I'm planning on brewing tomorrow, and my yeast is still in the fridge. I don't really feel like being up until midnight messing with a yeast starter. Debating if I should put mine off until Tuesday, but tomorrow I've got a buddy coming by who can help out. If I wait until Tuesday, I may or may not (most likely not) have the assistance of my roommate who has thusfar flaked on me 4/5 times.
I'm doing a Pale Ale that the my software says will be 1.062 og. Knowing my previous luck, it will probably turn out 1.058. I've got a whitelabs vial, and it sounds like I should be good, since they say they put plenty of yeast in there. Alternately, I just do an 6-hour starter.
Should I just pitch it, or take the time to make a starter?
