I upgraded my USB Pro kit over the weekend using this method, and it works great! Thanks for the great video.
A couple changes I made from the video:
I didn't do any soldering/de-soldering at all. My pads are already dual zone, and I didn't want to learn soldering for the first time on an expensive kit like this (although I know I should learn to solder). In order to get the foam off, i just used a fresh razor blade to cut a slit to the edge of each piece of foam, so I could remove it, cut it and/or reorder it without removing any wires. The large slit in the gray foam hasn't caused any problems for me while playing.
I made my own mesh heads out of fiberglass screening. They have held up good so far, but I may buy the billy blast heads if these don't last very long.
I used a small circle of the EVA foam as a beater pad on the kick pad. With that and the new foam order, I've really reduced the sound of the kick pad. The kick noise was by far the worst part of my kit previously.
Triggering has been great, and i haven't had any problems since the upgrade. The best part is the reduction in noise. I don't have to turn up my speakers or headphones nearly as loud to hear just the sampled sounds.
