Thank you for your reply Rhys. Hopefully I can help answer some of your comments.
The geometry of the 3-ring has been modified on the Dual Hawk main risers and the cutaway cables are also now coated with nylon, which together releave any pressure when cutting away. The Dual Hawk passenger harness has also been redesigned over the years to ensure optimal passenger comfort, our latest version is on display here at PIA. Most of the riser covers in the field that we are aware of, have no problem at all, but that said, having received input that the riser covers could be improved, I am currently working on a redesign that will further reduce the possibility of a riser cover coming open in freefall.
All that said, I realize that my opinion may be (obviously) consider biased, so I would be happy to put you in contact with riggers/gear dealers in your area that can reconfirm my comments, just shoot me an email at tandem@strongparachutes.com for thier contact info, and I would be happy to provide it.
Beyond those updates, there have been numerous other internal upgrades to the Dual Hawk Tandem System. Obviously, the basic design has not changed in years, because, well it works. That doesn't mean that it hasn't evolved as a tandem system. The Dual Hawk was not an adaptation of a sport rig for tandem, it was designed, from the ground up, as a dual passenger transport system. It was designed to be safe, reliable, durable and cost effective, and I believe it has lived up to those expectations over the years.
The point of my original post was to provide our latest newsletter with one goal in mind, to promote tandem safety. If you disagree with our "evolution" of the Dual Hawk, I would welcome your feedback. Please feel free to contact me at: tandem@strongparachutes.com or call me at (407) 859-9317.
