Most of the time I fish a 3/8, 1/4, and 1/8 ounce jig. The weight depends on the wind and how thick the vegetation is. The heavier the vegetation the lighter the jig.
As for as colors go, I let the light level determine that. Most of the time I'm using green pumpkin, black / blue, and black jigs.
I will try to match the trailer to the skirt, but I don't want an exact match. I like a little contrast in the mix.
I'll keep the sizes the same but either change out the trailer or hook it differently after about half an hour or so.
