Falcon Dual Layers ?

[BlizzardUK]

For the last 5+ years I have always made dual layer discs with Verbatims, the tried and tested, always work. However, I noticed today Falcon Pro Media have some dual layers, I swear by them for single layer DVDs.  They are £45 for 100. What quality are these if you have seen or used them ?
