for my ride, I used just a standard cymbal arm. I cranked it down, and it doesn't spin at all. Also, someone posted a link to a product that could be used in lieu of the pin (I found the "anti spin" pin to be in the way on the ride. I'd always hit it when triggering the bell.)
so, for me... I have the "pin" arm on both crashes, and the non-pin arm on the ride. Works pretty good, imo.
