First try, first line - and first success! Unbelievable!! :D
SPOILER: Start at r25/c7, create the main lightning - and then just make a "line" starting from r12/c14 and r12/c7. It´s not logical at all, but you´ll see a clear path and end with two "doubles" in left corner remaining, which is a piece of cake :)
