Obviously a lot of guys on this forum are not that familiar with ag options so let me chime in here. For option spreaders, grains are a pain in the ass because it's very difficult to trade calendar spreads because in some cases you are trading two different crops or at least two different deliveries. With the weekly options you can actually spread contracts not only on the same crop, but the same month. This removes a lot of the risk spreaders typically have with grain options. It also gives you really cheap ways to make directional bets on grains without worrying about limit markets. I think they will be very active and liquid.
