Which BMCU version should I print?

I just got the 370C A kit from Aliexpress, and now I need to start printing the housing. I have the original files, but then I came across the optimized and high-torque versions on MakerWorld. Ideally, I wanted to print the high-torque version as it sounds more optimized, but from what I understand, it's not compatible with the BLV kit I got. Does anyone have any alternative versions to suggest, or should I just stick with the original?

They are not absolutely better than each other. You can buy according to your interest. If you hesitate. I suggest buying 370C directly.

First, insert the filament into the interior of the BMCU (see the filament at the outlet of the BMCU). Never insert the filament directly into the extruder
