973 is planning on going with the ball shifters this year, and adapting them to their WCD. After talking with Adam, he said he might post a paper on what they are doing some time before kickoff.

In the meantime, I've though about changing the 3rd stage. While they have the default output ratios, you could easily adapt their other gears to get a little bit more reasonable direct driving speed. Also, you probably want to make a custom waterjet mounting plate to mount the gearbox too. This will allow you to screw your bearing blocks into this plate, and make an easy, customized adaption to your frame.

On the other hand, I highly reccomend looking at the new WCP gearboxes.http: //wcproducts.net/wcp-00100/. RC said he will release the prices for them soon, and assuming they will compete with the new supershifter prices, it might be worth the extra money for drive gearboxes that is made for running a WCD.
