I've never used a screen protector on my phone. I've always been insanely careful, kept it in a pouch or just not really cared. However, I'd like to go a different route with my Thunderbolt. I would like something that isn't "sticky" to the touch. Something very smooth. I would also like it to not blur the screen, I would like for it to be very clear. I understand there are many different kinds of types available, but I was wonder what some favorites are. Thanks.
