The solution came to me via the usual method I apply when I'm stuck long time on same level: I do a creative mess I know wrong, just to allow for new perspectives. And it worked again! Doing that highlighted to me that I can modify my way to go for a little piece of my 2 off path. I tried it after that on the 2 off path and won.
My old good method saved my life again. I should find a name for it... Proposals? LOL
