Doc, Abby doesn't know squat about heads so she instead suggests playing your backbeats at a slightly flatter angle and not hitting quite as hard. In fact, with the level of power you're using it's possible that you're losing volume through choking.
I've seen so many top players get their snare sounding strong without smacking super hard, eg. http://www.youtube.com/watch?v=SS6nhP5pX74
Refining your stroke a little might not only spare your heads but also add some extra tastiness to your playing.
