Here’s some factors that dictate choices for me.
Profile: A jig can create a big profile without a lot of actual mass. Adjust trailers to fine tune the profile whether it’s a baitfish or crayfish. T rigs tend to have smaller profiles but can be much longer when using a worm.
Rate of Fall: When slow fall is what I’m looking for, a jig is the deal. You can get a slow fall with a T rig with no or small weight but you loose the benefits of penetrating cover. It’s much easier to get a fast fall rate with plastics.
Penetration: Plastics get the nod when cover is heavy and snaggy, especially vegetation. I like jigs in wood however. There are jigs with screw locks however that provide bulk and more effective penetrating ability and less hang ups.
Action: If I’m looking for slower subtitles a jig with the right trailer. When wiggles and waggles seem to be a triggering issue the T rigged plastic shines. Lizards, Brush Hogs and such do great. There’s also something about the flare and collapse of a jigs skirt that just lends itself in cooler water. Like Catt, both in some form 24-7-365.
l like 7-3 or longer in MH, H and Extra fast. 👍
