Temporarily returning to the wenge project, almost every aspect (in both the visual as well as design sense) makes you go 'wow'. A truly inspiring build.
Ref the side topic of cocobolo, I've never had any reaction to it (but as Prostheta says, it is a sensitiser and, as such, a reaction can happen at any time and once you are sensitised that's it for life...) but it's a truly horrible wood to work with. On 'Tom's African Build' fretless I ended up using epoxy for almost all of the gluing jobs (in spite of trying acetone, etc, etc, to get normal wood glues to work) and it was truly dreadful to sand to shape. Once done, though, as ScottR says, it looks and feels beautiful!
