helicals question

Looking for opinions or experiences with using steep pitch helicals on both the threshing AND separation ends of a R72 cage. Spent some time laying in the cage this evening pondering this. Currently have 68 pitch at threshing end and since the sep end bars need replacing I'm seriously cosidering putting in the fast pitch type. Silly idea?

We did that in our R65. It worked very well. Moves material thru the cage faster and keeps material looser to allow the grain to come out.
Boy I would think rotor loss would be a concern. I talked to one guy that did it and he fought rotor loss. He did say it was great in green stemmed beans for through put.
Its backwards from what you would think. It took me a little while to wrap my brain around the idea. The best way I can explain it is since the material is moving from one end of the cage to the other faster, there is less material per square foot thus letting the grain out easier. The slower helicals causes more material per square foot across the cage.
