I also think it is best to fish and cook monks and that's what I do, but that's not the fastest way to get your fishing and cooking levels up. The difference is that the power grinder will end up with less cash than the casual player, but will achieve his goals faster. From that point on, it's mainly a matter of opinion and how you like to play the game. Say both start with 80 fishing and cooking, and 1 mil gp each. Both want 99 cook and 95 fishing, along with 10M gp. Who will achieve this faster? The one 26k tricking, barb fishing (or fly fishing, idk which one is faster anymore) and cooking sharks from 85.
