When your package is weak in one particular are, you should do your best to strengthen the other areas to the best of your ability. Units hired based on the whole person concept and how well they think you fit in. I've seen people get hired at units with less then stellar scores. As far as being competitive for this and any future board, I would suggest you retake the TBAS and try to get more flight hours if you are able to. I myself have not been hired by a unit yet, but have had a few interviews and continue to make my package stronger with the feedback obtained from those interviews. Lastly, one of the best thing you can do is to go and visit the unit. This way they can get an idea of who you are and what your motives are.
