He doesn't do hand to hand every single episode, sometimes more than once in an episode. Comparing them is apples and oranges.
And honestly, there just isn't a reason to change anything....it has all worked well, some don't like this or that, but the grand majority of people love, like, or perfectly fine with the suit as it is....and if Melissa is happy with it, cool.... as she said, "If it ain't broke, don't fix it". Also, they can still use some earlier flight footage in order to save money and time there to add some place else...and if there is too much of a change in the suit all of that flight footage is screwed. Yes they can CGI some stuff out and put some stuff in....but ask DC Films/Warner Bros. how much fun and cost that will be for Cavill and the reshoots they are doing....
