Joe,
Go to the stiger site and you'll see dive bombs. They are a weighted "lip" that attaches to your line or lead core. They have 1oz, 2,3 and 4oz. Every ounce gets you about 8 more ft. down. Ex: 4oz bomb on your lead will get you between 80 and 90' if you have the knot at the water.
Long story on the pro-am. I'll catch up to ya later on that. I think we'll be fishing sat. morning. I'll talk to ya on the water if you go yourself or give me a ring.
