A new DSD harness design features semi-rigid shoulder straps to improve shell alignment under load, addressing a previous problem where soft straps would fold during use.
An indexing bracket innovation allows all Euro-style carbon arms to be mounted ambidextrously on either shoulder, eliminating the need for arm-specific orientation.
New DSD harnesses include straight carbon arms without outward inclination, made possible by the improved indexing bracket's angle adjustment capability.
Earlier harness models used aluminum components that were not validated through engineering testing software before production.
Unvalidated aluminum parts can accumulate microscopic fractures under load conditions, potentially leading to component failure.
Engineering testing software can identify structural weak points and provide precise design guidelines to prevent part failure under operational loads.
The new DSD harness includes a single-piece foam pad and medical-grade inflatable bladder instead of single-chamber designs.
Transport bag, custom powder coating, and custom paint options are available for the new harness design.

Claims about structural defects in earlier models are disputed by other operators who report no serious failures despite years of use.
The assertion that aluminum parts failed engineering software testing is presented as the designer's assessment but not independently verified in the forum discussion.
Concerns about accumulated micro-fractures remain theoretical and are not tied to documented failure incidents.
The discussion includes unresolved disagreement about whether design evolution during product development constitutes inadequate manufacturing standards or normal product improvement.
