I have only done it twice. But, it is a very productive way to cover a lot of water. See my recent post "I'm rernt boys and girls". I use Bandit 300s (black and pearl most productive) and Gravediggers from Cabelas ($2.99 each). I don't use any special rods and I am not smart enough to manage anymore than two at a time.
Watch for post from Creekslick. His info has cost me about $250 in the last few weeks gearing up to troll cranks.
