I've got a real mixed bag of pretty ordinary eyepieces.
The one I always seem to gravitate to is my Meade 18mm UWA.
It's certainly lasted longer than a number of my scopes!
I too have a eclectic mixture of eyepieces: Celestron e-lux 25mm, SWA 20mm, ES 11mm and 6.7mm, a 40 year old Celestron 36mm plossl and finally a TV 24mm panoptic. Not surprisingly the panoptic is my favourite ep in terms of the quality of the image but it is also happens to be one of the more useful maginifications on my 6" SCT. I also find the old Celestron 36mm useful for wider views of the heavens and the ES 11mm and 6.7mm for planetary work.
My most-used is my Vixen LV50mm, a big 2" beast, on my f/15 Maksutov. On an f/10 SCT the equivalent is 33mm.
The next most-used is my 13mm Vixen LVW, this is very nice eyepiece and compared favourably to a Delos 14 mm. In your scope the equivalent is a 9 or 10mm.
I also have 5, 8 and 22mm LVW's; they're parfocal, 2" and all weigh about the same so no re-balancing or refocussing when swapping from one to another. The 8mm is occasionally useful in excellent seeing, though both the 8 and 5 are more ideal in my refractor (f/7).
On the big scope it's the 20mm T2 Nagler (the Holly Handgrenade) followed by the 13mm T6 Nagler. On the smaller scopes it's probably the other way around. For planets it's the 7mm UO Ortho.
Excellent eye relief providing me with hours of comfy observing without having to jam my eye into the glass. Plus, they are sharp right out to the edges in my short FL scope! After that would be my 14mm Denk followed by the 22mm Vixen LVW.
