Mid Thigh AKA Pinlock vs Suction for Young Fit and Active 30Y/O Male. Prosthetist Says No To Suction/Vacuum

Hey Guys! I had my Amputation Sept 2 2024 and have had my New Pin Lock Prosthetic for about 4 Weeks Now. I have noticed ALOT of Active AKAs in Suction or Vacuum and it seems easier... My Prosthetist stated that a Vacuum socket this early due to me losing volume over the first 12 Months would be a huge mistake as it would be a nightmare and probably wouldn't want to stay on.... I'm dealing with rotation and a slight bit of pistoning also. Does this sound right ? Anyone's Opinion ? Thanks
