Lots of times, people get hung up in playing the sand wedge from the sand. If you’re bunkered 30 yards from the pin with a lot of green to work with, take your 9I or even an 8I, don’t worry about the club digging (it will), and make a good swing.
The long bunker shot is one of the toughest in golf, and attempting it with a sand wedge will likely leave you in a dreary position. Take a longer club, a shorter swing, accelerate through the sand, don’t worry about the follow through too much, and play quite a bit of roll.
