Well, you might be weird or not but ...
With all due respect testing it out above water, unless you are standing up on the bottom, in a pitch black room or otherwise, is not the same as in the water and more-or-less horizontal. All changes, major or not, should be tested in shallow, protected, water and carrying all of your gear (including exposure protection) so you know "the system" still works. And while I am standing on the soapbox, one should never change more than one piece of gear at a time; problems can multiply exponentially when too many new variables are inserted into the equation.
