The original Sinn U1 rubber strap is a perfect fit on a Kemmner Octopus. I am looking for an aftermarket alternative with a buckle instead of a deployant that I could use on my Octopus assuming if it fits the Sinn perfectly it should fit the Octopus too, just like the OEM.

Curved straps can be hit or a miss so don't want to dive blind and get stuck with something that's not going to work.

Anyone has any experience with a good curved end that might fit the bill....Thanks
