I like both tanks, for different reasons, i like the streamlined covered gas cap. and i like the shape of the chrome capped tank. I have both tanks, but chose to use the locking cap one for my bike because i live in a city, and people like to take what's not theirs (ie Gas) yeah i know you can just pop the lines off the petcock and drain the gass out, but in my experience most people around here go for what looks easy, like an unlocked door, or gas cap. It realy all depends on what the rest of your build is going to look like, make sure your seat mates with the tank well, and either tank will look great.
