Mike, I have three suggestions:

1. When trying to learn to use both elevator and rudder start with quick four point rolls, this way you don't have the blending issue. Quick aileron to knife edge, opposite rudder...hold, quick aileron to inverted, down elevator...hold, quick aileron to second knife edge, same rudder as aileron...hold, quick aileron again to upright...done. For me this was the easy way to learn which way to input elevator and rudder. With the slow roll you have the blending issues as NJRCFLYER2 mentioned. Of course, you also need blending with a nice slow four point, but this is not what I'm suggesting to start with.

2. For relatively quick rolls don't start out trying to input both rudder and elevator, just do the pump down, pump up, pump down, pump up routine. Make sure you can mentally handle this and step #1 above before you start trying slower rolls integrating elevator and rudder.

3. If you have a flight simulator this is an excellent skill to practice on the SIM. Fly rolls close to the ground on the SIM so you can see how your inputs are affecting the plane.
