Siebert Outdoors makes the best jigs IMO.
Swim Jigs: I like anything from 1/4 oz to 3/8 oz I usually use some sort of white and some sort of color that imitates a Bluegill
Arkie Jigs: I almost exclusively use a 3/8 oz because 95% of the time I'm using an arkie jig I'm skipping it under docks and the 3/8oz works best for me. Colors I like a Black and Blue, Green Pumpkin, and some sort of Brown which almost 98% of the time is PBJ
Football Jigs: I use any where from 3/8oz to 1 ounce it all depends on what depth of water I'm fishing. I use the same colors as I do an arkie jig.
My biggest advice when it comes to jig colors is do not over complicate it. You do not need 100 different color of jigs. IMO you only need 2-3 colors of jigs. A black and blue, green pumpkin, and a brown jig of what ever color is your favorite (PBJ, solid brown, brown and orange, ect)
