There's more than one way to get there, and only you can make the decision. I did some trap years ago with a mid bead and kinda figure 8'd them for rising targets.
The best thing about the sights is one can tell if one's stock fits.In a private place, check and make sure your weapon is empty. Check it again. Close your eyes and mount your shotgun,and then w/o moving anything, open your eyes. If the gun's on target needing no adjustment, that stock fits. If not,then you have to play with it.
There's plenty of better trap shooters around, maybe they can explain how they do it better than I have.
