| Though there seems to have been enough answers already I'll throw in what little experience I have as well. Have dived with bow shoulder and cuff dumos and when it came round to buying one myself I went for the shoulder dump. I cant say anymore then that I found this to be a personal preference and I do prefer being able to adjust the flow rate on the auto shoulder dumps.
Also I have to agree on the DIN fitting, only ever sued A clamp until I bought my own but have to say I am happier with the DIN |
