The bulky part that worries me (and is why I don't use "bit drivers" usually) is right at the tip - it gets wider within an inch of the screw, which can be highly annoying.
I prefer the "longer bit" drivers that you can find (Milwaukee 48-22-2131 for example) but the best drivers in my experience are the screwdrivers with really long thin shanks.
