Cocobolo (or cocobola, etc) is the wood you're thinking of. It's a good hard wood, pretty similiar to bloodwood and purpleheart. However, like with kamagong (macassar ebony, great wood) sticks, your partner better have the same sticks or you'll shred them up. Rattan works well if you have partners with rattan or softer.
If you want to strengthen your hands/wrists by working with heavier sticks, go for the kamagong/ebony, which are the heaviest of the 4 aforementioned. All are fairly heavy compared to rattan, though.
Edit: I have no experience with the Bahai sticks. If I knew what wood it was (I don't recognize Bahai), or at least the family, then I could probably make a guess. However, I've never worked with it so I don't have a clue.
