REFLECTOR: VGs?

[Dave Black]

Moving right along...

I'm nearly to the place where I'll need to install the VGs on my wings. 
But I bought these 5 or 6 years ago when they first became available 
from Velocity. And I've heard that these particular VGs can become 
brittle in sunlight.

So, should I install these Factory VGs, or get some others which will 
last longer? If 'others' where should I get them?
