Currently my favorites are Viking foam pads for application, and Charisma's for removal. I use MF for QD'ing, and I always get it slightly damp first by spritzing it with a few sprays of distilled water until it is supple. YoSteve towels are great. The Zaino applicators are fine, also. Really it's a matter of personal preference so feel free to experiment a little.
After you remove the Z with a cotton towel, buff it with an ultra-suede MF for a super fantastic wonder-glow. Just make sure that your car is absolutely dust free (it should be at that point)... And if you have any smears, this technique clobbers them.
CMA has a new towel that I am going to try for this soon.

I like to let the Z2 or Z5 cure for a few hours before I use Z6. If you use Zfx you can go with the Z6 right away, from what I understand (haven't used it yet but plan too this spring).
