That is actually a very good option.There is another option if making the shot with shape is in question, play a safe behind the 9 and 8 balls. Or play to a safe on the 8 behind the 9 after making the 7.
Rotation is not like 8 ball.
To my mind 8 ball is closer to straight pool in regards to pattern play and nudging your balls out of clusters.
Many people don't realize the the object of 8 ball is not to necessarily run out, but to win the game.
A good safety with ball in hand and only 2 balls left on the table is a game winner.
