New Routine, No DOMS

[Kennysvgp08]

Yesterday I began doing Push pull legs. My workout was this:

Incline Bench: 5x5
Flat DB bench: 3x5
Arnold Press: 5x5
Lateral raises: 3x10
Overhead tricep extension: 3x8
Single arm tricep extension: 3x10

Usually on days that I did Chest/ Tris my DOMS were strong in my chest the next day. But today after this new routine, nothing.

My old routine was:
Flat bench: 4x8-12

Superset:
Incline fly: 3x8-12
Incline DB bench: 3x8-12

MultiSet:
Close Grip bench: 3x8-12
Flys: 3x8-12
Decline push-ups: 3x8-12

Skull crushers: 4x8-12

Tricep extension: 4x8-12

Dips (Tricep): Till failure

Any reason for this lack of soreness? I went till sweat was pouring down on me and I drove myself to failure. I understand it's all about pushing heavier weight each week, but do you think I should go back to my old routine? Any advice would be great bros!

The exercises I've done before. Just not in that order on the same day with those reps.
