I've been looking at these thing forever. Basically I decided against getting a new IC. However info form various members and vendors have made me think again.

Coming to the subject of the ARC, their Japanese site shows 3 models:
073, 079 and 073 wide.

Now I can guess the difference between the 73 and 73 wide. But does anyone know how the 79 differ from the 73? Seems to be somethig to do with the inner tubes or something...

Anyone??
