I want to use it as a finesse rig with my spinning rod and light line when is it good to use it what about weather and the plastics you can use is it good for right now in the winter

I use Grande Bass rattlesnakes, 4" flukes, or Hag's Tornadoes in shallow water. Especially if water is 4-5' deep with lots of grass a foot or two under the surface. Killer technique.

Anytime they are in shallow water. By the way don't tell anybody. Lol.

Did really well with the mojo post spawn and summer. Craws that fall with pincers up are good baits for the mojo. Also had good luck with ring fry and tubes.

I use it around the spawn. I'm not any good at seeing the beds or fish. This allows me to back off an area and cover it thoroughly. A 4" lizard or Baby Brush Hog are my first two choices.

Mojo will come through weeds Limbs & trash better than others.
