No problems. We need to get this right!
Have uploaded two more versions:
#37 - Still keeping the uppercase/lowercase but with the shaved treatment to the "z".
I know you're trying to retain the capitals from your old logo, but in my professional opinion I feel the lowercase letters actually say "fire abatement / retardation" more so than capital letters as they reduce in size. They also allow for a far much "tighter" logo, signifying a rock-solid dependency of the product.
#38 - The uppercase version. To make this work I had to separate the letters more than a "thin line" space.
The balance with the white in-line was crucial, and looked a bit silly otherwise. As in my comment with
#37, the spacing is now making this mark fall apart a little, and losing the more dynamic, compact aspect of the uc/lc version.
Hope you don't mind my 2ยข - just trying to keep the integrity of your logo in mind!
