I never suggested that you should give up anything. Not once, and of course you know that.
You purchased a 12 + year old DSS wing, produced using materials we haven't used in over decade.
You are of course well aware of this, yet repeatedly fail to include this information.
Current production uses much more robust bladder materials. These 30 mil bladders have greatly reduced the incidence of bladder damage in all of our wings, those with zippers and those without.
It's actually far more difficult to make wings without zippers. It requires a very skilled sewing machine operator to close the wing without damaging the bladder. Remember bladders are *larger* than the shell. That means the bladder constantly trying to enter the area being sewn. Your claim that zipperless designs are a benefit to the manufacturer is laughable, clearly you have never attempted or even considered the challenges in producing such a design. Of course that hasn't prevent you from implying DSS is somehow cutting corners and cheating their customers.
I suspect the reason why many wings have zippers is due to the fact that bladders, which are RF welded, and out shells, which are a "cut and sew" item are often produced in different job shops. Zippered designs allow for assembly in a 3rd job shop, install the fittings, bladder, hose, test etc.
Scuba is full of design choices based on available materials, or manufacturing resources, etc. that many mistakenly assume are based on performance criteria.
It's hardly a secret. We proudly point this out on the DSS website. Many prefer it. I'd suggest that most who recommend DSS Torus wings are actual owners and users of our products. Clearly they are aware of the zipperless design, yet somehow are able to over come what you choose to portray as a gross design error.
Once again we have the typical Scubaboard poster compelled to "warn" others of all the short comings of goods they don't own and haven't used.
Seems like more of an agenda, than public service.

PS: I owned a Ford once, but I sold it because I got tired of having to set the points and lash the valves every ~1500 miles
Of course it was a '63 F100. My mission in life now is to make sure others don't suffer the horrible same fate, so I make sure everybody know what they will be faced if they buy a Ford. It's the least I can do for the community..........
