Hmmm...that article offers some good reasons that Jay Turser chose the '54 P as their model to clone. I've heard many comments that the contouring makes it more comfortable to play than the slabs.
the contours only work if you wear your bass like a bow tie.
To be back on topic: I used to have a RI paisley P and I hated the fact it had the contoured body. Just not that beautiful and not original.
