How boned am I?

Kinda clickbaity title i know but I'm looking to IST to Kansas NG from Idaho NG and from what I'm reading on here and the absolutely nonexistent information I've gotten looks like I'm boned. Ive been in 5 years, 3 years AD, BLC complete and not getting E5 with my current unit, I excel in all areas except PT. My last evaluation was stellar but my lack of presence, associated with my PT score is what killed me the most. I've got 3 MOS' but would really prefer to stay 19 Series. The 155 is the unit I'm likely going to as I want to stay on Bradley's. How boned am I?

Edit: I guess i should clarify, how do I best go about setting myself up best for this IST. Do I have a decent chance of going as a 19C and getting E5 or am I gonna be stuck.
