You're retraining as a FTA with a line number for tech; which AFSC are you going for?

Congratulations to you! Yes, most people you meet think you got dropped often as a baby but either in because/in spite of the former you managed to blaze through the ranks of your first contract. As a result you have a line number for tech as a FTA but you also have the option to retrain this year. Which AFSC would you choose?
