Career help (USCG Rates)

I’m a Navy veteran (former AD -Aviation Machinist mate).

I plan on enrolling at Texas A&M’s Maritime Academy, and I want to focus on Marine Transportation.
I’d like to become a navigator eventually.

I’m trying to build my resume, and I’m interested in joining the Coast Guard reserves soon. My question is: Which rate in the CG would benefit my goals the best given the available billets open to me?

-MK (Machine Tech)
-MST (Marine Science Tech)
-ME (Maritime Law Enforcement)
-IT (Information Technology)

Any help/ advice is appreciated!
