thanks for the help everyone. i ended up building some some mounts out of steel. pretty simple design.. basically like a hitch/receiver setup. they work pretty well. managed to try em out this weekend on winnisquam. no salmon, but i did pick up a small rainbow.
i also grabbed some chamberlain releases too. glad i did.. the ones that came with the riggers didn't seem like they would work all that well. the chamberlains are really nice.
i run lures 8 to 20 feet off a painted ball, either chartruese green yellow or orange, the painted ball attracts fish close in. earlier when the line is much further out the lead or black color works better, no attraction for long lines out is needed or wanted on the ball
