I’ll agree to your sentiments about the dampener with the Kara. It was lackluster for sure when I briefly tried it.
Alu Plate + Internal Weight was quite nice, but PC + Weight was just as good if not better, but which combo being better might depend largely on sound/feel preferences and switch choice.
I have a dampener coming with my U80 SEQ2…so I’ll have an extra dampener…almost enough incentive to have a 3rd Rama board to use the dampener for and just be a Rama fanboy. XD
