I can say for larger drum size > 14", internal side triggers do not trigger well from the edge to center of drum. For that matter even top mount side triggers. You may want to take a look at
https://www.extremedrums.com/store/. Marshall knows his stuff and guarantees satisfaction. Great side mounted triggers. He even has extended mount brackets to slide the trigger closer to the center. But even if you get halfway, should be good. That would be beneficial for the Kick really. He shows a kit with internal side mounted as you expect. Very sensitive triggering.
Worse case maybe for the 10 and 12 rack toms you should be good. But anything larger, if'y.
Probably want to go with spider mount for the snare. But again, extreme use side mount still.
Unless Rob has settings that can get those side mounted triggers dialed in?
I DIY'ed like other, a spider center for the 13" snare, and all my toms 3 side edge triggers for the 12, 14, 16. the 10 left as 1 side trigger. Everything was dialed in with eDrumin.
hope this helps a little. Nothing is worse than spending the $$ and then have issues.
