My 4 string Thumb is good for rock, metal, and slap. Not as versatile as some basses. Wouldn't say it's so good for 'honk' (if you mean the sort of 70's funk/disco thang that seems more set up for Jazzes).
Regarding the Wenge/Ovangkol thing I would suggest you audition yourself, I don't find that much difference myself, if anything I prefer the feel of Ovangkol.
