More opinions, please...

Hi Dribbble, I need your help!
Yesterday I did a little poll to get some advice on a logo. This is the follow up question.

So this is where we landed after lots of crowd sourcing, and a client meeting . . . my major question is - is the shield still seeable? Or is it impossible now to judge since you've seen the other images?
'z' for Zoom.

Thanks guys! You're the best.
