The Secure Edge pads worked reasonably well for me, but still had some slippage. What I disliked the most tho was the amount of time it took to clean (and reclean) the lenses afterword.
I now use, with incredible success:
Clean all lenses first (except Alize)
Front side gets clear surface saver tape with blocking pad mounted on it
Blocking pads are PSI #2810
Back side gets an extra pad if it is AR/polarized/photochromic/otherwiseExpensive
Let sit in tightened chuck a minute or two to set adhesives before edging
Even tho it may sound like a lot of tape, what I really like is that when the lens is finished I just tear off the tape and no longer have to clean StickyStuff off the lenses. :)

PSI has a new blocking pad designed specifically for super hydophobic and oleophobic lenses call Oleo-Gold. It is brand new. If you would like to try some samples, email me at kgillen@looktopsi.com and I will send some out to you.

Holy zombie thread, Batman!
I have converted 100% to Big Red pads from Dynamic Labs. I've never had a single slip.
