Speeding ticket - mitigate or contest?

Basically, I was pulled over around midnight on the H1 East for driving 25 mph over the limit. The road was pretty much empty. The officer measured my speed using laser and recorded it at 75 mph in a 50 mph zone.

I want to believe that the officer may have exercised some discretion, as I was cited under HRS 291C-102 instead of HRS 291C-105. He easily could’ve been a d**k but was not. The total fine issued was $192.

This is my first traffic violation in seven years of driving.

Because my speed was measured using LIDAR, I understand that contesting the citation may be more difficult. This leads me to my question: should I admit the violation, submit a written statement, and request a Driver’s Abstract Non-Conviction (DANC), or should I contest the citation and plead not guilty?
