Terry,
Although more expensive than William Optics, I use the Tele Vue Standard binoviewer with the two arm power switch. My primary EP's are a pair of 24mm Panoptics with 68 degree field of view. Another good suggestion for less expensive wide field EP's would be the Orion Stratus but they are heavier than Panoptics.
The Tele Vue two arm power switch provides three different power selections with one pair of EP's so I rarely change them out for the pair of 17mm Stratus, which is my next step down in focal length. Not having to change out EP's also allows constant use of my binoviewer heat strips for dew prevention.
If you have already looked through a binoviewer you will have discovered that they provide a panoramic effect that takes one way beyond single eyepiece viewing. This effect is a trick played by your own brain but the end result blows you away. Also, since a binoviewer allows use of both eyes, you are much more relaxed and thus able to see more.
WARNING: Continued use of binoviewers may spoil you to the point you may never want to look through a scope with one eye again! Occasionally I go back to use of one eyepiece, especially for public viewing events and I find I do not like the old one-eyed view at all.

All of the Binoviewers should work very well with a C11. You will not need an OCA/OCS because of the wide range of focus in an SCT.
Because the C11 is an F10, you should be able to use most EPs without problems.
You should be able to use anything from 24mm to 10mm with your C11.
You may even be able to add a low power focal reducer to increase the field of view.
