I've used warm & plush on my last couple of projects. I have a long arm, so I can't help with the spray basting issue, I do know there is no scrim like W&N. Also, I thought that it had a softer? fluffier? finish than W&N which might make the spray adhesive more difficult to stick to. I really like the extra loft, I didn't make any adjustments to tension. I did note that it has to be quilted more closely than W&N.
