Does anyone make the equivalent of Taiyo Yuden Watershield disks in a blank BR?

The only company I have found that makes the equivalent of TY Watershield is Falcon Media. More specifically, you're looking for Falcon Media BD-R with Smartguard. It provides the same glossy finish as TY as well as the water resistant inkjet protection.

If you do a quick Google search on Falcon Media, you'll find many people agree that their discs are better than Taiyo Yuden. I use them for all of my projects and have yet to come across a bad burn.
