Glad you had fun!
I thought the 3 best options for you were:
- the route you took
- taking H to G after 13 (best route from 13-14 is going north along the forest line)
- taking C to A after 3 and the west route choice to 4. I was thinking that may have been optimal.
Either way, I'm happy it got you thinking!
Thanks for the ideas to check out and thanks for thinking about challenges for all the handicaps!
