Instead of a snubber I use either a foot long piece of 150 pound seine twine or parachute cord - much cheaper than the snubber and does the same thing. I also use a halibut snap to attach a 4 foot cord to a heavy Offshore release - the halibut snap clips to the twine so you don't wear out your cable and you can remove your release easily. The 4 foot cord on your release is so you can hit bottom with your ball and not snag your lure. If you want to stack lines or flashers get more 50 cent halibut snaps, don't bother with that $10 stacker release.

Use a 15 pound ball and get 400 feet of 150 pound cable - that way you will have extra in case of accidents and the 400 is only $4 more than the 300. Use a Penn clip on the end of your cable - it has a ball bearing swivel that allows the twist to stay out of everything even when under load, and if you kink or fray your wire you can easily re-attach the clip in the field with a key and pliers. Plus, the clip is plastic and insulates your ball from your wire.

Buy or borrow a microvolt meter before you buy a black box and check your voltage. Mine is a perfect .680 without box, but only if I use uncoated lead balls - nice because it saves me a hundred bucks and the hassle of a box, and the balls are cheaper. Since you have the same boat as me you might wind up with the same voltage.

The stuff I use is somewhat on the cheap side on purpose - you will lose gear, and that's good, because just like steelhead fishing, if your not losing gear you're not catching fish
