I was trolling the TD Vibrations in the suspending model, the color was blue & silver. We were trolling 2.2 -2.5 mph on 12 -15 leadcore with a 20 foot leader of 10 lb test. Those TD vibration baits are so deadly, they send the typical rattle trap to shame. I have done really well in some events on them. I think we were getting down about 30 feet down with the lead we had out but it is hard to guage with leadcore. I no longer fish events so trolling works just fine for me, now I know why they don't allow it !
