I'm kinda curious about this too, i know you should strengthen the lats and work on bar speed..but is there a certain main move you should perform on ME bench day to help with this? Maybe like.. a 1 board press?
I'm not a wsb guy so my advice is not suited for that but I would say your pecs are the lacking factor. The lats to me help press the bar right off your chest after that it is chest then tris.
Maybe you could incorporate some flyes into the routine
Not a bad point. In addition to what's been mentioned, perhaps using pause press and pin press to help exploding off the bottom. For working the chest, perhaps some illegal wides and 1-2 board presses with a cambered bar.
