Im used to pitching jigs and trigged creatures. what is best time/ situation to use these? should i go shakey head or trig?

I use them strictly as a T-rig presentation when targeting weeds and sandy/pea gravel transition areas.  There are much better choices for a large profile bait when pitching and flipping.  The Culprit is a ribbon tailed worm and really not suited for shakey heads as their action is geared toward moving the bait rather than shaking it in place. 

I used them with no weight. Just a hook in them. I just casted them out and reeled them with a pause. I used them in black shad 12" in the evening.

i like a very small bullet wieght pigged... 1/16 just to getting a down a little deeper..

I go with t-rig weightless, or if I need to fall a lil quicker I use this as to not affect the flutter action...
