Offshore boards and the OR16 clip installed in the centre position. The board will never come loose and you will not have to pull all the lines in, after catching a 12 inch fish, to re-set everything after you turn around to grab the board.
I have Church boards as well and they work fine. I prefer Offshore as the flag makes seeing the boards easier, especially in rough water and if it's too rough, just drop the flag and it will preform, just like a church board.
Just reel the fish in, until the board gets to the boat, keep the line tight, un-hook the board and reel down to where the board was, offering no slack line.
Again, having the board release with a fish on is crazy, especially when running multiple boards/lines.
