Hi ive recently ordered a heavy duty casemate tough case to protect my HTC One X as its gonna get a lot of stick in my job, I now need a really good screen protector the problem is I dont know which one to go for and the prices seem to vary greatly,

So what I need to know is: whats the best/toughest screen protector I can buy for my One S and will it fit on with my casemate tough case?

PS: If any of you know of a tougher case on the market could you please let me know, cheers.
