Jim, use you shorter rod for the inside diver, and use a mag sized diver set at 1, or 1.5. Longer rod for the out diver (I still like the mag here also)set at 2.5 or 3. My two diver rods are located 14" apart from each other. Run the out diver back at least as far (or farther) as the inside diver.
Tilt the inside diver holder down farther than the high diver.
Here is a shot of my diver holders. (Click on it to make it bigger)
Are you tangling with the Rigger? or you other diver?
You may be tangling as there going out?
It's best to deploy a diver at a slower rate than an open bail. Many guys lower there divers by loosing the drag, and letting it creep back.
The only time I had troubles with the two divers tangling was when the flees where heavy, and they loaded up on the braid, and pushed it back into the wire.
