I’ve worked with Zebrawood a lot and it’s very prone to tear out which I gather you are aware of by now. It’s also one of the foulest smelling woods when cutting and sanding! If I remember it grows on the banks of swamps which add to the gaseous smell! The good thing is, the smell will go away when it’s finished.
If you use a down cut bit you’ll get less tear out. I just started a new guitar with Zebra wings and I used a brand new carbide 1” template bit and it tore like crazy. I’ve noticed that duller carbide router bits with a router that wont bog down seems to help prevent tearing out. Also, if you push the router against the cut it also helps prevent tear out. I always like to keep a nice dull router bit on hand for when I get a pesky wood that likes to tear out. Sometimes it does the trick. Ultimately you should use a shaper and leave the router on the bench. Some woods just weren’t made to have their end grain router. LIKE PURPLE HEART!!!!!!!!!!
Just my opinion on Zebrawood.
My current project, Zebra wings with Padauk neck through, will have a rosewood board with a zebra headstock cap.
You are correct about the overall weight. It will be about as much as an old 70's Les Paul or slightly more but anyone interested in exotic hardwoods will be expecting some extra weight.
