Continuous Webbed Harness

[divbum]

Given your only problem is removing your gear at the surface, why create or invite multiple problems with extra d-rings, clips, and buckles.  I would focus on improving on the one.  And considering you really don't do much of this diving why a permenate change to your gear?
If the day comes down to safety and getting out of my kit I would value it as my life vs cutting a piece of webbing....  I can afford the webbing.

Because it was only mention that you tried everything.....  The difference between in the water and on the boat is the gas in your wing.  Deflate the wing, chicken wing your right arm out, then reach over and inflate the wing while pulling out your left arm.  Most people are to afraid they'll lose there gear to deflate the wing at the surface.  Clip on line from the boat to a d-ring if your not comfortable with it.
Rescuing someone with a broken buckle was one of my most memorialble trimix dives to dates, but I learned from it....

Good luck  find a plan and stick to it.  10 dives in 5 dyas tring something new each time will make you a jack of all trades master of none
