I had the same dilemma when I decided to buy. Both looked good, the AI chopper had better paint, but what sold me on the Dog was the handling. The Big Dawg will out manuever and out handle an AI all day long. Plus the speedo / tach combo on the Big Dog is much easier to read, reset and in my opinion, looks better. Not to mention, and a really big support for Big Dog, is this forum.
