I use that FB in my kettle and it works great. With WHOLE HOPS.
I have been completely changing my system lately going to gravity and then to a single tier in about 6 weeks time adding some new components along the way. I kegged an Ale last week and noticed my yeast cakes seemed to be about 1/3 the size I normally see. Poking around I noticed it was almost all yeast. Very little trub. Racked another beer into carboys this weekend and it was the same. Hardly any trub.
I thought back and boiled it down to the addition of the false bottom and dip tube which replaced the bazooka screen and tilting. The difference was incredible.
Back to your post, I see what you are saying with repeatability but you are in the Great North West. Whole hops!
