I'm going to come at this a different way. Back in November, you had finished a 16-week bulk where you gained 10 pounds. As of yesterday, 15 weeks later, you're already 6 weeks into "a 14-week cut".
You're bouncing around way too much, which is unfortunately common but keeps guys stuck in short-term thinking with slow piddling progress at a time when your body is primed for making serious leaps if you give it a chance.
Instead of a bodypart specialization, I suggest you take 6-8 months to put at least 50-75 pounds on your 10-12 rep maxes (not 1-rep maxes) for most lifts with each bodypart while making sure you don't drop a pound of bodyweight. Gaining some bodyweight would be fine (to be fair, I don't know your actual long-term goal, but I'm making an educated guess), but as long as your gym performance is consistently improving and you're not losing weight, good changes should be happening to your physique.
So, that's what I suggest instead of yet another short bulk-turnaround-short cut cycle with some extra incline pressing.
