I typically use a 3/8 oz swim jig in blue shad or grey shad.

What are you guys throwing?  Type of trailer?  Do you go with old stand by or since you are swimming it use a twisting tail?

i use a davis swim jig as far as im concerned its as good as it gets white and chartrues or black and blue i do havea couple in green pumpkin and orange i use a yum buzz frog cut long ways one the white and chartreuse black and blue a paca chunk in the same color as the jig and a orange curly tail on the green and orange sometimes ill use a stanley i believe hot foot frog on the green pumpkin jig

5/16 or 3/8 black/blue or black/blue/chartreuse or purple w/black stripes or green w/black stripes and black with chartreuse tips. I use various trailers with each one but I have been having the most success with a 3” grub, tail down. The grubs are green or black or a dark smoke.
Funny thing is nothing white has worked at all; but then again I’m fishing weeds. I’m throwing to the edge of the surfaced weeds and snapping it back as it sinks/hangs. I fish down stream, shallow to deep. I have caught very few fishing parallel to the edges, or from deep to shallow. I have caught even fewer fishing over 8’ deep.
Remember I’m fishing a strip pit so the bank in most places drops off from 0’ to, in some places, as much as 26’ in less than 15’ from the bank. Sharp, deep edges seem to be the ticket. My “secret” has been to keep the jig hanging up in the tops of the weeds and jerking it free. That’s why the fluorocarbon line has become so necessary to me.

I think your thinking of a Swim Bait Carter 

That brings up another question; Jack made mention earlier about “when the swim jig bite turns on here”. Are you referring to open water fishing Jack? So far I have not been able to catch any “open water” fish using a swim jig.
And Jig Man are you using those sizes later in the year? When the bait has grown up? This is the first year I have tried this technique but man I am lovin it!

Hoppy, when I am using jigs for swimming I have several tied on.  I start with my white/chart. 1/4 or 3/8 and if I don't get bit, I pull out the bigger darker deeper ones.

My favorite spot is a long point that runs from 3' out to 18' and goes to the river channel at about 20'.  There are tons of stumps on it.  If those slimy critters aren't up hitting the smaller jigs, I go for the big boys and knock them off the stumps.  I don't have to wait for them to settle and the big jigs don't get hung up as bad in rocks and stumps as the bitty ones.

Last August we took 34 bass in less than an hour and the 1 oz golden shiner with a gray trailer was the best.  The next night I caught 17 in about 30 minutes on it with a 4# smallie and a 3# smallie in the mix.

Geez Jigman.  I'm going to have to let you teach me how to fish.

G I've been trying to for years.

Its always worth trying Getfished.  It has become my #1 go to bait the last couple of years, far exceeding the spinnerbait.

Brown or Green Pumpkin work well as a bluegill imitation.

Steve the head type may make some difference in grass and weeds  but I know guys who only swim football jigs.

When the water is in the bushes I like a 1/8 or 1/4 oz. jig instead of a spinnerbait.  I swim it up to a hole in a bush, stop it, twitch or drop it then move on if no bite.  That is the same way I fish a spinnerbait but the jig is way more subtle and gets me more bites unless the wind is crankin'.

The 1/8 really isn't that small.  I use lighter weedguard but the same size hook as in the 1/4.  Here are a couple of pics if 1/8, 1/4 and 3/8.

I landed 3 and 4 lb spots on 1/4oz. light wire hair jigs at Lake Martin for years and never had a problem.
