Very cool solution. My first try was 6-off, but then I saw a 4-off that was very close to the correct solution, and was able to work it out from there after a little fiddling. Fun level! Nice process.
The_Qwerto's 126 is such a smooth path. I don't know why I had such a hard time, finding it. :))
My first tries were so faaaaar away that I didn't even want to remember, how far. lol :))
