Richard,

If you pull with rudder applied, your flying path will most likely be incorrect.

Best way to realize who to look at a certain condition is using a small (stick or anything) plane to visualize the path and attitude of the plane.

As GW explained above, rudder is for correction only in this discussion.

1/2 Reverse Cuban Eight, Flying left to right, wind from back. >> Keep right rudder for straight flight line. This will steer your plane slightly to right (skidding attitude).

Now visualize your plane from top it will be like \ >> (the bottom of this back slash is the front of your plane although it is not that much).
If you pull elevator with rudder applied, where will your heading be?

Your heading will be inward causing more correction.
You need to release (or adjust) the rudder right before pulling, so that the plane pulls at the attitude of straight flying along the flight line without any tilting.

Once pulled, re-apply (or adjust) the rudder for wind correction to keep the path.

release rudder, 1/2 roll to invert, apply left rudder to stay on path.

release or adjust rudder to loop and stay on the flight path to finish the manuever.

I am not 100% correct here because releasing or adjusting rudder make differences.
You will have to familiarize yourself to many different conditions.

So, go out to field and burn fuel.
