Most top pros in Taiwan use SW cues (ebony forearm), and as I heard, all of them are DPK or Jerry era SW's, I am not 100% sure though, hope some one would correct me.
Kevin Cheng's cue (the one he used in the US Open)is a '98, however, at the Derby he was trying out a cue that Bob Meucci made for him.
Both Ko's' cues are post-2000 (2000 and 2006, iirc).
Yu Lung Chang has a DPK with an old yellow micarta ferrule.
I didn't ask Jung Lin about his SW, and he sometimes mixes it up with another cue that he favors (might be a Carmelli, can't remember at this time).
