I do want to express though that I was expecting more banana flavor...BUT, I did something very different that might have affected the banana's play in the brew. In the secondary, While the banana floated at the top of the carboy, I gave the entire carboy a couple good spins, kind of swooshing it all around and down. I did this maybe 2 times a day, sometimes everyday, sometimes every couple of days. But I noticed that right after swooshing it around, the yeast started feeding like crazy and the banana started fizzing, bubbling through the airlock crazy-like for another 5 minutes or so. Eventually, after a week or so, it was as if the yeast was completely eating up the banana, as the volume of banana floating at the top considerably decreased by the end of the secondary.
Most of those bubbles where probably just CO2 offgassing. Swirling likely gave the bubbles some new nucleation points and forced a little bit of the gas out of the solution. A lot of folks witness this when dry hopping with pellets. Lots of bubbling as new places for the bubbles to form are introduced into the beer.
