I asked the engineer to give his expert take on the subject of plastic/polycarbonate and you can see what he gave.
I'm not sure what the big hang up here is. Just because people are getting hung up with the term plastic or whatever. If it's a strong and durable product that's going to improve the Z's lighting capability, why not consider it? Nothing wrong with taking a by and clinging to the old lense. There will always be some that are unwilling to try some new improvements or want to maintain certain oem integrity. I can appreciate that. It's all about choice in the end and that's what Andy's offering - a choice. Until now I'm not sure if the Z32 community had a choice about this particular lighting deficiency. I'm glad that there's one now. Let's not try to focus on the initial messenger, but on the message itself.
