Lug Nut Sizing

I'm looking to replace my OEM lugs and caps and I know i'm going to go with the McGard black chrome lugs.

So far i've gathered that the right size is M12 x 1.5 but the last thing I need to know is do I need bulge or non bulge?

I've seen in some threads that non bulge may not hold the wheel correctly since its hubcentric, but others said the non bulge does fine.

Which is right?

Bulge or non bulge?

Is there a difference in price? If not, just get the bulge-type and remove your worry.
