Good test video ... You mentioned about the sound difference. I fly MAS prop's on a Mavic Pro Platinum, and have found that the rpm is lower with the MAS prop's than with the DJI stock 8331s. The effect of the lower rpm is to reduce a bit of 'buzz' in the sound of the drone and make it less intrusive. I don't know if you observed (either on the controller display or in flight logs) much difference in the rpm during the hover tests????
