Yobuck, I use rods 90* to the boat when I troll jigs and cranks. Cranks and I haven't gotten along down here yet but i haven't spent much time trying to figure out why yet. Size of crank probably. My rods are the same length as yours and run 6lb line. Also set up a couple of 6' to fill the holders. I use Hi-Tek rod holders and have no issues with them at all. Rods parallel to the water works best for me and keeps the line out of the wind better. Having the rods spread out from front to back would make me move a lot and that's getting tough on some days. Keep after it and you'll find the best way for the way you fish. 1/16 and 1/32 jigs work best to me. Super slow with floats works with that setup too.
