    My Hollis75 sidemount trim works best with weight pockets put on each shoulder. I have 2 pound weights in each. I do not need a weight belt, but I do have tank weights (I use Aluminum tanks) and it helps keep the tanks streamline too as well as proper total buoyancy . A sliding D-ring would be better, but I have not found anywhere to buy one.

      Hi Ted, it is common what you are doing to trim out your Hollis SMS 75. The wing has much more lift higher up the body than a true side mount only harness like the xDeep Stealth Tec system. The Hollis SMS 75 has more in common with backmount BCD and wings in this respect. So the reason you are needing to add that weight higher up is to counter act the high lifting point to trim yourself out. Personally I would recommend a true sidemount system that lifts from lower down for most people, having said that there are some ladies that will benefit from the lift being higher up the body.

    Thanks, exercising a bottom gas sharing situation, I found easy to pull out the long hose and ascending to the first stop. I easily switch to the left deco cylinder. After my team mate switch to his deco, I found that oxy cylinder (secondary right cylinder) make me difficult repositioning the long hose. I keep training on it, thank you for your reply and useful videos.

      Thanks Freddi, it should always be easy to deploy as it is for an emergency situation. The re-stow like you are doing as a technical diver holding a stop is great for a diver in training “skill building and discipline” plus a challenge to restow and focus on staying in position etc. If a real problem existed the re-stow is not that important if it cases a technical diver to blow a stop because they are busy trying to look good with nice tidy hoses on cylinders if that makes sense, the importance should always be on the team safety and the long hose can be re-stowed on the surface if needed or at least after all decompression and stops have been completed. Cheers, Steve
