Just a thought Kerry, why not combine the 3-way swivel with the snap-weight.
I've done this. Take a 3-way swivel and attach mainline to one side with your braid and a good swivel.
Clip your snap weight to 3-way ring or use a another snap-lock to attach. If your worried about weight hanging in rocks and losing whole set-up, use a short piece of mono line that will break before braid.
Run a 3-4' leader other side for your lure of choice.
Snap weight should be easy to unhook or just leave on while you bring in laker.
I'm sure a little experimentation will give prove what works best.
Trying to unloop braid 50' up the line from lure/fish would be a hassle.
