The USDA-ARS station not far from me has documented approximately an additional 1.3-1.5" of available soil moisture by using a stripper head. In our area of low rainfall (~16") that makes a pretty big difference. We purchased a CX84 to run on a 1688. This will be our first wheat harvest with it, we are about 10 days or so away from getting to try it. Jon and Phil if you have any suggestions on settings I'd be all ears -- my email is good if you want to go that way.
lots of good info on the Shelbourne site, setup for a specific combine, Maintenance , settings , etc.

Remember to change the gear box oil every year and use only Mobil 1 full synthetic 75 / 90.
Run the header low enough so the stripping rotor can reach the lowest heads. Once you find the right header height, set the hood so the tip of the grain heads are about level with the top of the hood nose. This will bend the heads and tops of the stems forward far enough to present the "wall of straw" in front of the stripper rotor, so any seeds that fly forward are bounced back into the stripper rotor.
Bending the crop forward like that also causes the crop to spring back into the rotor in a way that the heads will be stripped off and thrown over the rotor into the table auger instead of out the front of the header. ( see drawings under "design history" to better understand this)
Lots of good info under "how to set up your combine." Stripper rotor speed, concave mods, etc.
For our little IH rotor machines (1480) in hard threshing spring wheat, we need to run 3 cover plates on the front of the LW concaves to keep the much smaller amount of crop material( remember, no straw to add bulk to help thresh the grain) on the concaves long enough to get a complete, white cap free thresh. we also need to run the rotor faster and concave much tighter than recommended for a conventional header.
Run as fast a you can,(ground speed) the harder you push that header, the better stripping job and less grain will be lost. More so if the crop is thin.
We run spec rotors with Stewart Steel auger fronts for an AFX type rotor and use 12 Gordon threshing bars on the front of the rotor.
This gives us a rotor that will eat green peas or soybeans without much rumble, yet do a very good job of threshing tough threshing spring wheat.
We run Harvest brand, large wire concaves for all crops, just add or remove cover plates depending on seed size and how hard it is to thresh.
The Shelbourne site tells how to determine what stripping rotor speed is correct for your crop / conditions.
