I use Zagg InvisibleSHIELD for everything. I usually use the original ones although I opted for the "no fingerprint" one this time. I have heard multiple reviews about the EXTREME one not being as responsive to touch so I would steer clear of that one.
The only place I have found that you can get the front and back so far is Zagg.com and they are back ordered through Oct2-9th.
