I found a only few posts talking about the Edge 2000 foam pads, but they were off topics under other threads. I know OCDetails likes them a lot. Below are 2 links with more info:

I am currently using the regular velcro foam pads, but the back velcro portion tends to warp over time and not make full contact with the velcro back plate. Also, it is hard to get it center perfectly and at 5,000 OPM, it comes off sometimes. I think The Edge 2000 will eliminate these problems.
I would like to learn more about the Edge 2000 from users (edit: and anybody's opinion). What should I buy to take me through most of my polishing needs w/ my PC7424? They are more money (especially since I already have the regular velcro pads and back plates), but I think it may be worth the investment.
