I hear you, the bore is good and large. My question relates to how the regulator section is contected to the square block. Given the difficulty that some users have in rotating the barrel on a standard DSV from AP Diving I can imagine that the user will use the regulator as a lever.

If they do in deed use the regulator as a lever to open and close the mouthpiece I wish to ask if it could cause stress/leakage between the square block and the regulator block.

I could be well off the mark as I can't see the whole design.

I promise to improve my English....
