Hello there! New to this board but a long time TFW2005 reader. Started Transformers just about 5 years ago. Seen many people been asking whether to get HA BB or Cannon BB I don't really have a Cannon BB with me but I have the normal type. Here's some photos I have taken. A few comparison Featuring Sam plus the Camaro's Interior Bumblebee's Head Comparison with other ROTF Class Obviously, the detail on HA BB is definitely way better than the deluxe class of BB. But when it comes to sizes, the deluxe class of BB is accurate while the HA BB is not accurate at all. Nonetheless, if you want to gather you ROTF figures in group, HA BB is not what you are looking for (unless you don't mind inaccurate sizes). If you just want to have an awesome BB, HA BB is your answer. Hope this helps to all of you~!
