1) Is there anyway to get a really close shave out of the Norelco? It's always shaved my face every bit as close as a blade, and I honestly had very high hopes for my head....but I can't get there. (more time to let my skin/hair get used to it, more pressure, etc?)2) If using a blade, how do you make sure to get all the hair/stubble and avoid leaving anything behind? 3) Is the HeadBlade the weapon of choice for a lot of you, or is there something that is easier to use?4) Last, and most important, how the HECK do you shave without cutting your neck and back of your head? It may sound funny, but I really don't like bleeding...and I have to suspect that the little nicks now adorning the back of my skull don't look so hot either!!!!!!
