Suck it up and pay the ticket. Unless your in danger of loosing your licence or the points will get your insurance to cancel you, it easy just to pay.
You took your chances and got caught. Don't let it bother you, lots and lots of people get tickets. Doesn't mean they're bad or evil, they made a little mistake and got caught.
If you do fight the ticket; take traffic school if offered to you and never, never never say you were speeding. If you admit to speeding, then you will be found guilting, regardless of the reason. If the ticketing officer didn't give you a break, then the judge or traffic commissioner won't either. And never, never, never lie in court (and an ommission is not a lie).
