I would recommend Fermcap-S so you most likely won't have to ever deal with a blow-off.

It depends on the yeast strain. I learned this the hard way on my last batch. 10 drops of Fermcap in the fermenter did nothing to contain the Wyeast 3787 I pitched. I even dropped in more once the krausen climbed up to the airlock and it would not subside.
is that the weizen yeast cause that stuff goes ape ****.
and then use a 5 gallon fermenter?
I think I would still want a 6 gal fermenter. When you siphon you always leave some crap in the carboy. So to finish with 5 gallons in the keg you need 5+ gallons in the carboy. Get the 6 gallon fermenter so you have extra space for the eventual bottom of the carboy crap. The 5 gal fermenters are best for long term secondary where you want to reduce the oxygen contact.
Is there a reason for switching out a blow off in favor of an airlock once fermentation subsides?
