Clearly the accolades for the FA 84 EDT are exceptional. This ski is on my current wish list. With respect to length 184 v 176? I am 6'4"' and 225# taking my location and frequent hills out of the equation, what would the size recommendation be? Current ski Dynastar Contact 4x4 178.
IMO, 176, per all the above comments.
My time on the 184 at 6'2" and 195 leads me to believe that the 184 is for Axel. I found it somewhat ridiculous in all instances except ONE very uncrowded, perfectly groomed day at Sun Valley.
If you like the longer length and radius of the 184, I'd think hard about going with the non-EDT version (Pro? Ti?), even at your weight.
