If you want to spend the money on riggers go for it but I feel it is not necesary on the western basin.I have developrd a system the last couple of years that is deadly on the eyes and catches few junk fish using Offshore boards with tattletales that have been modified and Inline weights and spinners.We have used this system since the jig bite ended and only once did it fail to get our limits of eyes.{six out of seven}I agree on the decent rodholders and also the six trolling setups.A word of advice here.Make sure your rods are all of the same length and brand.Makes it a lot easier to read the rods just in case you pick up a small fish.The system described above requires that your boat will troll speeds as slow as 1.3mph.If you want to know more just let me know.
