Both are great blades. A lot of pros use both blades. Look at Wang Liqin. He uses the Stiga Rosewood. I personally would go with the Rosewood because it is all wood. I like al wood blades better than carbon blades. You get more feeling and control from all wood. So I like that. The Rosewood is also a great blade for looping with a lot of dwell time. I like that also. Someone mentioned Ma Long. He used to use Timo Boll Spirit. Then he used Timo Boll ALC. Then, in August he switched to an all wood blade. Since he did that, he has not lost a match.
But it all really comes down to personal preference. I would also say, the first pro ever to win a world championship with a carbon blade was Zhang Jike. All the rest were using wood when they won the worlds. That is also worth noting. That being said TBSpirit is one of the best carbon blades out there.
