I like colours and you're getting much closer with #22. Perhaps try a grey, or softer colour with the "hub" part of the text. And somehow shadow, or connect the "2" between the N's. I'll try and post a suggestion as a general post.
re entry #76: can you please try the N2N part in a slightly more vibrant/darker blue? A colour somehwre between entry 36 and entry 76 perhaps? I leave it to you. Thanks.
re entry #88: really like. If you have time can you try (using same font):
- different two colour only variations - just to see what it might look like in different colours - slightly larger gap between the letters "N2N" and "hub" - Slightly larger/higher swish (or loops) above the letters
re entries 153 and 152: thanks for trying. can you do with the swoosh the same size top and bottom please. Size of swoosh to be somewhere between entry 153 (top) and entry 88.
Also, try colours red (N2N) with black (hub), and blue with orange - always keeping the "hub" in smaller/thinner case but nice and close to the N2N letters like in entry 88.
Also please try blue and grey like you have, but with slightly brighter shade of blue than entry 88.
Can we go back to the basic design of entry #88, but try a few more versions: - using the colour of #154 - using the colour of #156 - using another blue in a similar part of the spectrum
