Quite a large number of operators have had good success with the fixed airfoil chaffer, since it directs air straight up and allows more air than others. It's also good in other crops, as well. Another alternative would be a fixed opening (.101") cleaning screen as replacement for the bottom sieve. Check with gwill@holtonks.net for airfoil chaffers, and jvord@hotmail.com for cleaning screens.
