Since I already had a different 35" scale bass, it wasn't that hard of a transition for me. The neck and body feel "big" compared to my other five string, but I don't have any problems switching between the 4 and 5, both of which I use in a set. I have more trouble with the string spacing when I make the transition than I do the scale.
The 5 string neck is thicker than a Ibanez or Pedulla, but thinner than something like a Warwick. I haven't messed with Fender 5 string basses too much, so I don't know about the feel of their necks. I prefer the feel of the 4 string Skylines over either a Fender P or jazz.
Like I said, the 55-02 will do a very close imitation of a jazz, but the electronics lack a little of the zip. Just keep that in mind.
Of course trying one before buying it is preferable, but they aren't the most common brand in the world. Sam Ash used to carry them, but they don't any more.
Not to pump my own band or anything, but if you want to hear what it sounds like in a live setting, watch this.
And this is what it sounds like recorded:
