Since your hybrids have soft leading edges and low centers of gravity (i.e., more weight toward the bottom of the club), they allow you to skim across the surface of the bunker and get the ball airborne without you having to help the ball up or take too much sand. Grip down an inch to offset the fact that your feet have dug into the sand, and stand tall with your arms hanging loose and relaxed. Line up the leading edge of your hybrid with the equator of the ball. When you start your swing, pretend there's something very sharp under your chin. It's a good image that'll keep you standing tall so your club doesn't dig into the sand.
