Wait, we can have thick spacebars now?
Not sure yet, I'm still waiting for response from Hammer.
But, personally, I don't recommend going with thick Ti spacebar. A regular one weighs about 17 grams, and it's already pretty heavy. I don't know how a 27 grams spacebar will feel like.
The reason people choosing thick PBT caps is because it feels more stable than the thin ones. But this theory is not quite true on Ti spacebars.
