Thank you for your response Mr.Thibaudeau
I tend to believe my muscularity that is used for the bench press is fairly balanced at the moment. I tried to fix various different "weak links" in the past year however with no success. I did lots of upper back, tricep, shoulders, incline, dumbells, dips however nothing really helped. That's why I want to go back to the thing that made my bench "strong" in the first place.
I normally fail around mid range, not direct over the chest but also not at lockout. According to some articles this means I have weak shoulders and should do incline bench press, however for example when I could bench 150kg I could bench 140kg on the incline.
Back when my maximum was 120-140kg I had 2 full layer sessions per week on the normal bench press ( looking back not optimal :P) and my bench just "felt" strong, especially on the eccentric...
I think I will use some "old" layer variant for bench and another for the incline bench and see how it goes.
