Since the 5-mile is a very common choice, I decided to add a 5 sub-hex version of the quad to the Kreations page. Check it out if interested.
I also did a little clean-up on the 7-hex version I posted yesterday. The newer version (downloadable at the same link as before) is straighter and the file is slightly smaller.
Let me know if you’ve got any ideas for improvements or other versions.
