My t-rig baits depend on the situation. Most of the time i use #14 test (Excel) with an 1/8-3/16oz weight on a 6 1/2 foot rod. I peg my weight with a peg-it and use alot of tubes and small craws. Wide Gap Gamakatsu hook 2/0...
When i'm really getting deep in the cover i'll use 3/8-1/2oz weight with 17-20lb Mono (Excel) or Fluorocarbon. I like the craws and bigger tubes for flipping myself. I always use my 7ft rods for this and they are either MH-Heavy action. Wide Gap Gamakatsu 3/0-4/0 hook..
When things get thick/weedy and the fish are kicking my rear end i'll go with the "Gorilla Tackle" and pull out the braid and 7 1/2ft stick. I usually use a straight shank beefy Gamakatsu or Owner hook for this.
When things are tough i'll use my spinning rod 8lb test with a smaller soft plastic bait and a 1/16 to 1/8oz weight on a 1/0 Gamakatsu hook. JMO.
I think it comes down to whatever works for you....
