Substitute Clueless Special #2

Again I started with a puzzle generated by JSudoku and once more just added a single clue to "tame" it, i.e. to get rid of many advanced techniques.

Rating based on required solving techniques: Tough
My personal rating based on actual solving: Hard

The first one is REALLY Hard
It took me more than 4 hours
But I really enjoyed it you have to jump in and out of the clueless!
The solution is

Be careful what you wish for!

When solving it I also had to do far more jumping between the grids than usual, but it did not take me that much longer than usual
My personal rating based on actual solving being Hard is because of all the jumping between the grids.
