I just got an EF Vanishing point as well, and I must say that this is a great pen and the nib is truly excellent. As Oranges and Apples said, you need a very light touch, but if you do, and if you like super thin lines, this is the pen to get.
I use it for my extensive note taking: I need thin lines for marginalia, and also for my written notes where I like to write a dense page where I can contain notes for an entire book on one 8X12 sheet (one or two sides). The Vanishing Point EF is the best note taking pen there is, in my opinion, and I have had it only for a few days now!
The advantage of the EF is also that the tiny cartridge lasts much longer than in an M or a B nib, so you need to worry less about making sure you have replacement cartridges.
I am considering selling many of my other pens, mostly because I have decided that a VP with an EF is pretty much my < $500 grail pen.
I was concerned that the EF nib might be scratchy and so I purchased mine from J. Mottishaw who adjusted it for 6/10 flow and no-pressure touch. That was, however, only because I was so sure that with a good nib, this will the pen I use most. From what I hear, Pilot/Namiki QC is so good that most nibs are great out of the box.
