First thing is there are no fish in La Jolla, so no need to worry about rods and reels
Second, it is about preference. I've done what a lot of peolpe have done, read all the hype, went out and bought a lot of gear (A LOT) and ended up with maybe 4 set ups that works well for me. This lead to my thin out of my Gargage full of gear
It also depends on what you are targeting that day on the water. if you are not targeting something in particular, then you need to bring more gear to handle different scenarios that may pop up.
3 rods for me in la jolla, Jig Stick (super seeker, diawa 20), spectra set up (Diawa or Avet on a Seeker), and one extra loaded with mono (i use this as my back up/ sabiki rod/fly line etc)
Go see Joey at Squidco, he and his crew will help you out!!!
Good luck out there!
