Amazing series!
A very hard touch, here.
Now I need to bring it from my 175 to the 163. Don't yet see, how.
EDIT1: Got it to 167 and now badly stuck, at these 4 off. Can't see anything faster, at all. Will be back.
EDIT 2: I later found another 167, and was still stuck. Today I found one two of, and soon after, another one. Was stuck for a short while, again. And then I found an 163. And then I found another. lol
But I don't think there is more to cut, and neither do I think it's any worse, because of the two possibilities *****************************************************************************************************************.
