I just installed the AWR RMM (70 duro) two weeks ago. I *love* the way the car shifts, it's so much less mushy. NVH is just fine, there's a little rumble at idle when cold--that's it. Nothing offensive. My wife rode in the car a couple days ago, she didn't even notice it was different. But I notice it in the way the shifts feel, every minute I'm in the car. And, frankly, I like a little rumble to remind me that I'm sitting in the midst of an impossible machine.
It was my first mod, and I would definitely do it again. AP+Stratified stage 1 will be coming soon. And my driving is mostly like yours, OP (and I have a very, very long daily commute).
I doubt you'd regret an aftermarket RMM.
