I was looking to have the front release with the OR39 pop open with a quick snap when fighting the fish as well as eliminate the board from trying to track straight ahead as you bring the fish in. You would only have the back clip on the line after releasing the front OR 39, the board would not be able to dive with a big fish, and you would be fighting fish versus fish and board. A number of times we would have to let the board fall back so it wouldn't track into the other sets as we reeled in. The OR 39 would eliminate that issue and I just need to know if anyone is using it on mono.
