It's now 5 years since you posted, but this looks like a case of "knowing before trying". I've seen quite a few people that "know before trying".
I've been using Okoume in my very high end builds. It has a very resonant tap tone, works well (a little tough on bits, etc), sands nicely, although needs a little bit of grain filler sometimes. It looks very nice as a natural solid body, and also takes lacquer finishes well.
I play every guitar I build it at least one show or session before I put it up for sale so I can be sure that it does everything the way I would want, so I can tell you with great certainty that it's a wonderful tonewood for the Jazzmasters & Tele style guitars I build. They are very light and resonant, and transfer their resonance very well through the pickups & amps.
