Also, when you get a chance, could I see a version where the background is black with the characters in gold? often the brochures may have back backgounds... but light will be likley the more prevalent background.
I like the "G" front used in 91 & 92 but it seem a bit busy in front of the "H" -- how does it look to you toward the back? is the "G" lost in the back or could that also work?
also, in the EPS file, could the hanging wire be "turned off or on" -- soe uses of the logo would not print that well -- I like it for many applications, but maybe not all.
I'm used to layered TIFF/PSD files, not sure if EPS works the same with various elements on their own layer??
