If I was going with my secondary scope [LX90-10] I'd go with:
30mm ES 82º
7mm Pentax XW
The 17mm 92º has a noticeable pincushion effect in my SCT. It's flawless in the Apo, but the Nagler performs better in the Cat [in my experience*]. The 7mm Pentax is a knockout at 357x with a very clean image for such a high magnification. 5mm Pentax is just too high [500x], and I haven't been able to push it that far yet. It's also flawless in the Apo. Some eye-p's just work better with certain scopes, but magnification isn't always the key factor.
