Honestly the default setting is pretty darn accurate. I print through WHCC and ACI, my prints through WHCC tend to be a little darker than the way it looks on my screen, the way ACI prints is pretty much spot on though.
Always remember the whole reason to calibrate a screen is to get it to match what your lab is printing. It doesn't do you any good to have a "calibrated" screen if it doesn't look the same as the prints you get from your lab. Each lab is going to be slightly different so focus on that instead of what the spyder is telling you.
