GC to US Passport?

[FA_1982]

HI. I need advise regarding my status to file for Naturalization. Here we go:

My family and I have been lawful residencees of the US since 1985. Every member of my immediate family is a US Citizen except me. I went to grade, middle and high school here. Until one day I decided to go to college in the Philippines. I managed to graduate in 2004. I understand that the immigration only considers your continuous residence for the pass 5 years. Basically, it would mean 2001 from our present year. Every summer while I was studying in the Philippines I would be back to work in the US. I did that for 3 consecutive years. I am now in the US for good working as a flight attendant that does US military charter flights. I am havin issues travelling all over the world since my passport is of my nationality. At times I would get by by showing my crew badge but nonetheless its such a hassle. I am considering filing for Naturalization this year (2006). In addition, my job requires me to be out of the US for 15-20 days a month travelling for the Department of Defense. Considering the sum total of my physical presence is greater than the time Ive been away from the country plus my job duties every month. should I consider applying for Naturalization?

Although I have broken my continuous residency, I have some factors in mind based from my research to prove my unintention to abandon my permanent residency)
1. I can prove my ties while I was away from the US as my parents filed my income tax returns every year since I started working at 16.
2. I can prove my job description as my company has provided a letter regarding the type of contracts we do for the military and the reason why I am away from the country every month.
3. I have documents from the college I attended.
4. I have been a resident of my parents' household ever since in which they have previous bills, mortgage and bank statements under their name to support this.
5. I have bank statements and credit card bills since I was 16.
6. I have registered for the civil service at 19 (2002)

Setbacks:
1. In the last 5 years I have been away for a sum total of 27 months however I have been in the country for about 35 months till today.

I am even not considering writing down my trips to the Philippines since the space provided for in the application will fill up from my travel based on my work schedule. And if they ask me, thats when I'll mention it.

I understand that this situations like this are based on the discretion of the interviewing officer. Now, anyone in this board know of a similar situation that filed for naturalization and was approved. And if I hire a lawyer, what can he/she do since approval is based on the officer. pls help.
