Should we fill out FAFSA and/or CSS if we are only seeking true merit aid?

Thanks. I have had some conflicting information and couldn’t find answers by googling. Fordham had requested FAFSA and I called FA office and they told me I had to fill out the forms and that it was required to get any aid including merit. I wrote to our regional admissions committee rep just to check with her and she then said they recommend it but that I can request a FAFSA waiver. I got the feeling that they recommend it because I may think I won’t get any need based aid when in reality there may be additional money that is need based that I would not get if I did not ask. Example would be someone making 135K, or even 165k. I absolutely know I won’t get any aid if there is a whiff of need base associated with it. However, I am a single mom funding it all myself and 250k is a big bite and I would certainly appreciate any discount that merit aid could provide.

I called FA again and got a different person this time and they said I can request a FAFSA waiver and still be eligible for the NMSF aid of full tuition. So, varying information, which is why I am seeking any experience and info here.
