The Ohmega works very well, and incredibly, cheaper than a RW. The amount of bend in the rope is adjusted by the position of the dogbone on the attachment point. It’s a tight fit, and using a dogbone with a rubber insert doesn’t allow it to rotate on the pin.
It’s mostly stainless steel for...
Sent it in with a couple others, the 20 year old XTC broke at 5020, it has a break strength of 6,200 lbs. Came apart at the end of the tucks and the where the core strands end at the end of the tucks. The buried tail, a fid and a half, broke at the same spot, and was melted solid.
The Lockjack is a good idea for MRS, the rope has to attach to the device to activate it, or a rope wrench device is needed.
The Sulu Go works similar, but on a single rope, stays open until loaded, it rotates closing the two rails, or sleds.

Another that...
Just a free running sheave on the Cric.
The tab on the spacer of the Ring Open would need to break before it could spin, but one of their rubber stoppers slide over it would keep it isolated.
Overhand on a bight below the friction hitch was used mostly back in the day, with a carabiner in the loop.
Low friction ring could go in the Butterfly, or a ready made Secret Weapon is the Cric.
Another splicing method might be a Tuck Bury, I’m going to send this one for testing, hopefully get as good of results as the Class II ropes.
The black rope is Teufelberger’s Rescue Assault, parallel strands with an inner cover of aramid, is the next challenge.
Courant’s low profile splice doesn’t have any of the core strands going through the eye, Teufelberger’s Drenaline SPlife has a quarter of them. A longer cover tail bury is suppose to make up for the decrease in diameter, but apparently the stitching plays a bigger part than other splices.
