There was a link on the ITTF web page. http://en.729sports.com/index.aspx
Looks like they don't just make table tennis stuff, they also make rubber railway sleepers for high speed rail tracks!
There's a long list of players on the Chinese national team that used 729 products - unfortunately the last one was in 1987.
Their whole line of rubbers and blades are listed (but the descriptions are far from enlightening). Oh wait - Batwings is listed (called Pu Ji Dui Tao) but XL isn't, which reinforces my suspicion that XL is 729 sheets bought in bulk and repackaged by another company. And their "euro-sponge" versions (with the leopard face on the cover) aren't listed either. And "Sky-wing" is shown with the "Sky-King" packaging!
Blades... lots of blades listed, but again the descriptions leave much to be desired (especially if you want to know the woods used in the blade). Take for instance, the A-3:
Product Name: A-3
Number of /ply:7
The thickness of thickness:6.0mm
The weight of /weight:88 + 3G
Handle type /handle:CS/FL/ST
Two: skin of Catalpa bungei
Three skin: Paulownia
Core board: cork
Cork sandwich plate special, reduce vibration, a ball plate feel good, strong stability, good tensile impulse force, easy and making violent fast loop drive.
What's Catalpa bungei? http://en.wikipedia.org/wiki/Catalpa_bungei
For the C-1:
Product Name: C-1
Number of /ply:5
The thickness of thickness:6.6mm
The weight of /weight:83 + 3G
Handle type /handle:CS/FL
Dough: white wood
Two skin: Mehmet Okur meters
Core board: Paulownia
The ideal floor suitable for modern all-round player attacking and defensive harmony, the bottom faster than traditional defensive plate velocity, but not the lack of stability.
??? (Mehmet Okur, it turns out, was a pro basketball player from Turkey, who played in the NBA).
Product Name: F-5
Number of /ply:5+2
The thickness of thickness:6.2mm
The weight of /weight:86 + 3G
Handle type /handle:CS/ST
Two skin: Aus
Three skin: 3K carbon
Core board: Paulownia
High performance aromatic fiber, offers faster speeds and increase lethality. Suitable for continuous attack near Taiwan professional athletes.
The 3K carbon makes sense to me.
