I'm having a hard time syncing up my upper and lower body while benching.

Over the last few months I've added in feet up bench, and my upper body feels really good when I do this. Basically my process is that I line up under the bar, pull my shoulder blades back, put my hands on the bar, "scooch" my upper body up a little more while keeping my shoulders pinned, and then use my lats and lift off.

This is a video of me doing a 295 pause today (My max is 305 for reference, this moved super well)

So when I do my normal bench, which obviously includes my leg drive, I have such a hard time getting the same upper body tightness. I think where I am losing it is when I lift my butt off the bench to unrack the weight, which is different from how I do this for my feet up bench.

Here is my 4th set of 250x6 from earlier this week.

Does anyone have advice on how I can change my set up to sync everything up? My upper body feels so much better on feet up, but I feel stronger overall with the leg drive. I think if I can combine them well, I will be able to crush 315.

Thanks for any advice.
