Consider a North or Slingshot bar with metal parts.
Metal parts are not an improvement.
The most reliable chicken loop release systems are not the ones with lots of metal parts.
When sand and salt and snow and mud and ice are a factor, the more basic chicken loop release like Ocean Rodeo, and Wainman tend to work with no chance of failure.
Ice, snow, salt, mud....made me shiver just reading it and remembering this past winter's sessions. That said another important point is to make sure you can pull both safeties and reassemble your loop with your gloves on. With 5mm gloves on stuff gets difficult real quick.
