What size Tub for adult BPs?

Just curious. Im about to build a rack and I am starting the design phase right now. I am just curious as to what size tubs everyone uses for their adult BPs?

32 QT for males and 41 QT for females :D

The three of mine are in 41qt tubs. They're each between 750-800g and I just toss in a couple hides for them. They're thriving fine and they'll all fit in the same rack once I build it. Seems everyone has their own opinions on size, this works for me so I'm fine with the larger tubs. :)
