I do think it's too thick, but at the camera bump. I hate, hate, hate, the massive camera lens bulge. I'd be happy if they even went back to 11 and 12 camera bump dimensions.
As for Pro models weight, it went down on the 15, then right back up on the 16..so they solved it, then unsolved it:
13 Pro - 204g
14 Pro - 206g
15 Pro - 187g
16 Pro - 199g
I never liked the weight of my 13 Pro. It wasn't that it's too heavy, I just didn't like it. I equally don't like the weight of my 16 Pro, and even though I didn't pay for it (my employer did), I regret picking it over the lighter base model 16 at 170g.
