Essex Question, Specific and Urgent (not another crank thread!)

[Godbody]

I've been planning on getting a precision for a while, and now I have a sudden need for a new bass before the weekend (long story, mostly irrelevant). I already own an Essex jazz, and I want another.

That means my options are the Ursa 1 http://www.rondomusic.com/URSA1MN3TS.HTML or Ursa 3 http://www.rondomusic.com/ursa3mnvwh.html

Here's my problem: I don't trust the "measurements" on Rondo's site. Can somebody tell me definitively if there's a difference between the necks of the Ursa 1 and 3? Or, are they the same neck?

If there is a difference, I plan on ordering the model with the slimmer neck, since I heavily prefer jazz-style neck profiles.

Any US-spec SX I have owned has had a fairly chunky neck. The necks on the Ursa 1 and 3 would be the same, theoretically. But as you know, if you ordered 3 Ursa 1's say, the necks would be different between all 3.

The J-style basses have a slimmer feel, perhaps thats the way to go if you can forgo the Precision style body.
