I agree with your uncle, the cop already cut you a bit of a break and in my experience judges are less forgiving.
If you go fight the ticket and the cops (there were two right?) show, what's your defense? unfortunately you don't have a leg to stand on and the judge may be offended you are trying to further get away from something you were already given a break on. Just my opinion though. Good luck either way!
