I assume your looking for big halibut, IMHO you should go out of Homer. Yes, everyone takes big halibut all along Cook Inlet from time to time, but i still think chartering out of Homer is your best bet.

As for big kings, it's timeing your trip to go on the right day much more than who you go out with! Also, some years are a lot better than others for bigger fish. (bigger returns of fish)
