BF are a PITA to clean, make hoods etc for, and the distortion in the cornewrs when viewed from the front ,make things cockeyed. As neat and panoramic as they may appear, they just are not my cup of tea. I bought two 16 ga BF, for a super low price, and often times go to bed hopeing I wake up to a cracked tank just so I can get rid of them.....Its a whole lot easier scraping up and down from outside the tank than it is horizontly inside the tank
