Using call spreads to increase gains/losses?

I’ve been looking into call spreads to try to increase movement/ dollar invested. Basically, I want results to be something along the lines of for every 1% a stock goes up or down, I want the spread to go roughly 2% in the same direction. I’ve modeled some spreads and it seems viable except for the role IV plays in options prices.

Are there other strategies which would produce similar results but not be as tied into the IV of a stock?
