So guys, finally went to the court... plead not guilty and reduced to 75/65. $235 fine. I guess one lesson is to not trust those so-called traffic lawyers. Most of them wanted to charge me $400+ in addition to ~$200 in fine... DIY FTW!
On a side note, the ADA who was in her 20s was gorgeous... So for the future, if you want to speed, go on I-87.
