The Perfect is pretty close to dead center on the balance point. I haven't had trouble with it, but then I shifted to it after learning on the nails first. Keep in mind the balance point being at the mid point of the knife doesn't mean it's at the start of the handle, which in this case is not at the mid point. That's why I often hold it with my finger further up the spine as I mentioned before - also why I wasn't too keen on the Pro from looking at it.
Yes, I did wrap the nails with a few different things, all of which worked well enough: cord, duck tape, and tennis racket grip tape, which is my favorite for the fell, but not very durable. I've got some pics on another post in this forum. I'll look for it.
