From what you are saying i wonder whether you are working with your wax too cool.It should run freely off the spatula but obviously not too hot. Creme wax can be difficult to guage especially if you change waxes.They do have different working temperatures.
Try your wax slightly warmer,it will spread thinner and you may find you have less sticking and it will use less strips.
