All over wild figuring. 

Mica,
This is Steve again. I like this one too! but I notice you have 2 pics...I like the lower one. Does this on cost extra?
I promise... the 451 stock and the 652 stock would be the only ones I would choose.
 
Thanks again!

Steve , the lower picture looks like a close-up of the bottom part of the top picture.  I do believe these woods cost more than the regular ones because they are thicker and specifically cut for  Tribute guitars; Mica of course will be able to tell you how much more.  
 
Have fun with the planning of your bass.

Hi Steve,
 
Valentino's right, the Coco Bolo tops in the Tribute section are extra-thick to allow for the carved top on the Tribute guitars. It's double the rate to use a double-thick top.
 
The lower picture is just a detail of the upper one.
