Perhaps, it is not really a problem, but I agree with DA AquaMaster: it can be an advantage to avoid any cavities that could collect salt deposits and silt. If you are careful rinsing or soaking it is not a big problem (we have been dealing with it for decades), but it does tend to protect a spot that is not easy to inspect from the outside.
Also i would not even consider MK 11 with the V250 second stage, Why? because the Mk 17 /V250and Mk 25/V250 most likely come as a package and will be a better deal,
The MK17 Would be my chose for all conditions.
If you want to take advantage of $ savings go with the MK11/S555 this makes more since.
I would think hard and get some pricing before you purchase.
DA Aquamaster knows alot about scubapro ,so ask lots of questions.
