I think you would be happy with channel iron setup as mentioned in all forward bar topic above in your crops. I believe hyper has pictures or recommends channel on at least the thresher side over in hyper mods. I do believe channel would be especially better on thresher side in corn for I believe it preserves more room between helicals to allow cobs to roll. It is probably not as important to do anything with seperator helicals for they are shallower pitch than thresher side (we have allways went all the way accross cage with either channel or shimmed when doing the job). Hopefully someone else will let you know how they did theirs if they are using the high low bar setup. We have not did any high low setups for I believe the main reason for that was corn and corn wasn't or isn't a big part of our crops especially for the guys still running P1s.
