The facts you refenced are sound but it doesn't follow that 775Pros are the wrong answer.

I believe a lot of top level teams will have great success this year using the 775Pros in their drivetrain. This year weight is probably not the huge driver that it is in many years so I don't suppose it will be as common as it would have been if teams were fighting for every gram.

Even so, I would not make blanket statements predicting failure when I don't think the data necessarily support this conclusion.

FWIW, you will have much less margin for error when it comes to overheating your drive motors but that does not mean that good teams with sound engineering can't find a way to make it work.

Our team has used the 1 775 and 2 CIM setup per side for several years now, where recently we've swapped out the 775 for the Pro version.
We actually have an AM Supershifter setup where we modified one side of the transmission plates to add the 775pro.
In the past we've gotten away with the 1 AM Planetary 1 CIM setup and it was fine also, back when the no. of CIMS that could be used were much less and we needed them for other functions of our robot.
We have tried running 775-550 with Planetary combo before. That didnt turn out well. The drive sounded nice, but stalled out very quickly.
