So changing from a BAG motor to a MiniCIM gets you ~45% more power but with 200% more weight. For comparison, a 775Pro is rated at 130% more power and 12% more weight to a BAG.

If you don't need 215 watts, a BAG motor is a lighter and smaller alternative. If you need 215 watts or more, than the BAG motor isn't the right choice. Overall though, it's an excellent motor for most small mechanisms on robots.

Your forgetting about the reduction. You need roughly 4x the reduction for a 775 pro compared to a CIM. More than often this requires multiple reductions (with hard to find gears) or a VP adding weight, complexity and size.
