Wrap
Wow! You are going to have a gorgeous cue when it is finished. I recently picked up a beautiful Blackcreek Titlist with very similar veneers. It has a chocolate brown lizard wrap.
I would go with a green on white speck Courtland as my first choice (if you can find it). I have also seen brown on white speck and double brown on white speck that would be a great combination with the color of your rosewood (especially after it is sprayed with finish). I don't know about the single black on white though, I believe the single brown would add a nice, but subtle warmth to the cue overall.
Please post pics when it is finished.
