Well, because that's what the OP has for one, a 4" arm. It's gonna make torque and doesn't need the help of the air gap down low that some are suggesting. JMO for added clarity.

I have a victor on a 360 and it works just fine with a good convertor. We tested an AG against the victor on my 360. The AG was better to about 3800, then the victor took over IIRC.
