Buda, as you know myself and Alchemy just went through two different FSDO's for the CFI and both of us came away CFI's first try. It sounds to me that the reputation of the FAA as CFI applicant slayers is fast fading. I convinced a CFI student who had been putting the ride off because of fear to go ahead. I told him if I can do it so can you.
I say to you Buda, take the ride and you will be nervous as you have mixed expectations. Go for it you atleast you get a shot for free!!
