I beg to differ. 14min may seem long, but it really depends on the bean and 
the roaster. A stock Sivetz (both 5 & 15# models observed), the mother of 
all fluid bed roasters, roasts Kona to City/City+ in 11 to 12 min., 14min 
would be hitting Full City or a bit darker. Some beans like Kenya I 
routinely Rosto roast 15min Full City to smooth them yet doesn't knock out 
their acidity.

Depends.  There are a lot of different fluid bed techniques and
machines.  I regularly roast that long or longer with the ubber
popper.  I think it all depends upon how much control you have over
the equipment/process.  For awhile I was going out to 18+ minutes to
get more of the drum style roast - worked for me.  I'd probably still
be doing it except I started to miss a little bit of the brightness
that I was giving up.  Before I get a lot of flak - I'm not saying
that I can duplicate a drum roast - just that I can move the roast in
that direction.  For my espresso blends, I am currently doing a 13:30
minute roast to hint of second that really trips my trigger.
In fact it's time for a little of the Donkey.

I would certainly defer to you on that. Maybe I should have said -
in my experience if I were to do a 14 minute popper roast it would
have turned out flat. I had 11 minute popper roasts that were flat.
Although it would probably take some effort to make Harar flat.
My main point was the difference between the two methods used by
the person posting and relative profiles.
I'm one of those who doesn't like Kenya (yet) but I need to try
a longer roast if I can bum some beans off my friend Peter.

Uh Ohh!  I must of missed something while learning to roast!!  I didn't know
that you could roast something until it was flat.  Maybe I will put some
harar in my WBII and take it to City+ in 4:30.  Surley it would be bight
then!!

Well, actually if you want your beans flat it's easier to just step on 
them:-)
As far as roasting the brightness out resulting in a flat cup I do agree 
with Jeff, you can, and I have. How long is too long varies greatly though. 
If I roasted Kona with the same 15min profile I use for Kenya, the Kona 
would indeed be flat tasting to my palate while the Kenya sings!
Now as far as "surley" beans go I'm not sure... and was the "bight" bite or 
bright!:-)

OOOPs  I meant to say bright ;-)
So, is there any kind of rule of thumb as far as profiles or ramps are
concerned with various origins?  Or is it mostly by trial and error?  I
guess I got too concerned with grassy tasting beans that  wanted to make
sure they were roasted.  After all of this being said, I'm almost positive
that is what happened because I'm sure that my 14 min. FC was lighter than
my 12 min FC, but the lighter didn't have the fruity brightness like the
darker did.
HMMMMMMM!!!
