Hi Steve,
I assume you are lucky enough to be going on a live-aboard charter with the boys from LPB? If that's the case you'll have an excellent time.
David & Rudy are definitely of the school that believe that big poppers, big splash, big presence attract big fish. They have the results on the board to back that up. I am sure they would be recommending large faced chuggers from the Hammerhead, Craftbait and Fisherman stables. Likewise large sinking stickbaits that have a lot of presence in the water along the lines of Orion Bigfoots in the largest sizes.
Whilst I agree with them that these lures will bring results, you really need to bear in mind that it is absolutely exhausting to effectively work lures of this size for extended periods of time, quite apart from the fact that you need rods capable of handling these lures.
What I found to be the most sensible way was to spell yourself by alternating between the big guns when you were in an area that had that big fish smell about it, then swopping to more manageable sized poppers & stickbaits in the 150gm range. Of course its always going to be Murphys Law and you'll hook up to a monster when you are using the lighter weight outfit, but believe me there is no sense in exhausting youself by working I-cup Hammerheads all day only to have the big mama hit you at 5:00 in the afternoon. The lactic acid will kick in and the arms will lock up and you'll be in every kind of trouble!
Anyway - numbers? You never really need as many as you think you should have. For a 5 day live-aboard you could no doubt get away with no more than 10 poppers, maybe a few less stickbaits and 4 or 5 pencils. You don't absolutely have to outlay huge dollars on the Hammerheads/Craftbait/Fisherman even though they are proven to work and nice to have - the Heru/Nomad/Blackjack range of Cuberra poppers in 125gm and 150gm are excellent and easy to work, and the same brands 150gm stickbaits are also proven lures at an acceptable price. Also the FCL Ebipop's in 140 and maybe the 200's. The FullScale range of Kongs have also produced very well in New Cal.
If there was an absolute must have for me in New Cal though it would have to be the Fisherman Bigmouth 220HP Tail, maybe the 200 of the same. They work in the environment that David & Rudy will put you in. Also the Orion BigFoot up around the 200 area. Can be hard to find though. Also you don't want to work these all day!
Whatever you take you'll have a lot of fun and hopefully come back with arms longer than when you went.
