Well Pat, I like the S now (though it's hard to see in the small preview). Weeding out small areas like that is kind of critical but I think if I were to make this as a die-cut I would eliminate the blue around the FAST anyway. Don't get me wrong, the blue needs to stay there but I may need to do some dicing to convert it into a single color decal. But I would also have issues with the "fast lines" that are coming off the tail since they are so thin (both objects and cut lines). But as previously stated I think with this design I would be happy with making a decal that is essentially a solid black slanted rectangle with the left side being circular. I actually think the shape of the decal may be kinda sweet looking so lets not even focus on coming up with making this work as a die-cut style decal.
But I still think I like #43 better (for the most part). I really like the more metallic surface look that the FAST on #43 had. The
#33 I think has about the right brightness...kinda a cross between #43 and #46. The white on the #46 just seems to make it have less character. And with the matching white .com right after it, really makes the website look like it is "fast.com". So that idea is out...I'm not sure if toning down the .com would work any better but I definitely see some possible confusion about what the actual web address is if I used this logo. So probably scratch that idea unless you can think of something to make it work.
I do like the solid black "decals" though as this appears that they letters have been weeded out of that part. If I was using a white background a shadow would really make that appear as if it had been weeded out.
