Any advice on reclassing to CMF 35 (either 35F or 35G) ?

I'm currently in the 35G course over here in Ft. Huachuca.
Of course you need a TS Clearance, a decent ASVAB score, and some patience.
It's a 24 week AIT, with 3 phases.
They've upped the game with some new learning materials, which doesn't make it an easy course. You'll have to be some kind of a good briefer, but as I hear in the main Army you'll typically have the foxes do that stuff for you.
I've got less than 3 weeks until graduation, and what I can say from the process is that there's a steep learning curve between phases, and there's typically a lot of pressure in making products fast, being able to cram and remember everything within your 6 months here, and be a reliable source for the GEOINT community.
PT standards aren't too bad, but between Foxes, Tangos and Golfs (the 3 mos's within the 305th MI BN) Golfs have the rough edge of it, yet it isn't as bad as I imagine a combat mos to be.
Training shouldn't be any problem compared to what you'll get after you mosQ. You'll learn much more after AIT, and get a lot more notoriety.
At the same time, your goal and mine might be a bit different. I'm trying to put in my 8 years and possibly get out to be in the NGA or something of the like.
As a Fox, they like to say they steal our promotions, but that's foreground work. A 14 week course with little to actually learn if you're going to be a mosT (as far as I can tell).
I say that for the education you should get that Golf contract, but I'm biased.

I was a 35F for 10 years and in my last MICO worked with both. 35G is doing some really interesting stuff right now. If I were to choose at this point, I'd probably go 35G.

Lots of powerpoint slides....
