The marlin bite has really slowed after Ernesto, but there were several seen yesterday and a few released...whites on all counts. I'm affraid with Florence and now there's another Tropical Storm following her path, that the bills may be gone shortly...hopefully not, but..!!
For whites, troll dink ballyhoo naked. Having TLD 25's or something light work best becasuse more than likely you'll have to drop baits back to them and that's easier on a TLD then a 50...not saying it can't be done. Whites will come close to the boat for baits and are not shy, so pulling the dinks on the flats close to the boat work great because you can see them come into the spread.
For blues, skirted ballyhoo, rigged squid pitch baits, or big lures by themselves or infront of horse ballyhoo or spanish mackeral will do the ticket. They will go after the small baits, too...you just need to hope the baits are on the right gear. Blues like the short rigger position for some reason. They can come into the spread and play with baits or just nail it and run, where whites normally smack the bait first to stun it and then come back for it.
You can also run squid teasers in front of your flat lines along with dredges down under the baits to tease the fish up into your spread. These are just what most guys pull...not saying other stuff doesn't work. I've heard of guys catching white marlin on a green machine behind a Boone bird this year(Felix the Kat

) along with blue marlin on big squid spreader bars early in the season. I think one of the whites caught yesterday was on a spreader bar since most of the charters were running tuna spreads, so it just goes to show anything can work.
Hope this helps and that there are marlin around when you get out there!! Safe trip coming home and have a beer for me while you're down there in Curacao!!
