The hood is 6' and has an 8" round exhaust riser on the top to which I will reduce to 6" and hook up a vortex fan. 
Why are you reducing it?  8" diameter is almost twice a large as 6".
Brew on

My guess would be because his vortex fan is 6"

good question tom - but yes, I've decided on the 6" vortex fan since it has a max CFM of 449 (which I am adding a control to lower when full power not needed) but the 8" has a max of 747 CFM which is considerably higher than what I need.  I can of course mod it with a controller - I'm not dead set yet, but being that the room is A/C'd, I want to be cautious of how much air is being sucked out.

Just a speculation but if you have enough air flow you should not form condensation.
What fan are you using?
I have 6" pipe and 250 CFM and that is not enough.

The condensation will be from steam exiting the kettles.
I believe he absolutely will have condensation.

I had a Jennaire Stove with indoor grill I vented it out the crawlspace to the vertical
exterior wall.  I neglected to use flashing on that wall, Long story short Water
made it's way in around that 6 inch vent pipe and rotted 2 joist ends and about 3-4 foot
of Sill Plate...so make sure you use flashing around those exit ports on your vertical walls.

I recently built a hood and used the Vortex 6" fan and it worked great. Humidy didn't raise 1% and you couldn't even smelled that I brewed beer in the basement when I was done. My wife was very happy about that. The only thing I would suggest is drilling a hole in the bottom of the fan for it to drain. It will drip constantly during the boil.
