A lot of this depends on how you like the edge performance of your C925. The 17mm is a "magic" focal length in my C925. The 138x magnification works very well and I can spend most of the night with this eyepiece. But I prefer the 17T4 Nagler over the Ethos in my SCT. Even though I have a great C925, the edges of the SCT are a little soft compared to my refractors, so I discovered that I didn't need that extra FOV.
I also prefer the Pentax 14XW over my 13mm Ethos in this scope - same reason. Plus it has a slightly brighter exit pupil.
This is merely my experience. YMMV.

PS - The Ethos eyepieces work like gangbusters in my refractors. Their super sharp, magnificent FOV really knocks me out.
