@boogieliciousit seems like adding a tiny bit of lead knee and ankle roll back and forth to your PP should help free up your lower body a bit more. In fact a small trail knee/ankle roll in unison can't be a bad thing either.
Record your practice. Learning a new feel takes time and patience. I’ve had roughly the same looking swing for a couple years now. It’s been this year when I’ve slowed down more, been even more specific with the movement and checks, that I’ve seen results.
A fun drill you could try for the grip and transition is to pre-hinge. Basically take normal stance and setup with the club, then while keeping posture and trying to keep your hands in about the same space, hinge the club up in front of you. Then swing the arms and body to the top of the swing and into hitting the ball. Let me know if you don’t understand that. I can do a video tomorrow, if needed.
Received these today (a dozen ProV1). Tried them out on the Mevo+ on the E6 Connect app, about 30 shots. The ball flight that is displaying seems the same compared to other balls. This was in short indoor mode (9ft ball flight), imagine that could impact the numbers a little. Also wonder if it might read any different on the FS app (looks like you can add the type of ball you’re using)? I’ll have to try that out later this week.
That all said, I’m no expert on the numbers or what they should look like (beyond my typical carry distances, which are being accurately reflected). Maybe I’ll log the numbers one of these days and share.
