Speers-Waller Series 3 13mm Eyepiece
This is my second S-W eyepiece (I acquired the 9mm Series 4 a couple of years ago) and I', a fan. My experience is that certain eyepieces seem to favour certain celestail object. In the case of my 9mm, it provides spectacular views of, among other things, the Orion Nebula. The 13mm is a perfect saw-off between magnification and field-of-view for double star splitting in our 8" dob. They provide excellent eye-relief (as advertised) and the optics are crisp. I think Canadian backyard astronomers have an excellent home-grown option in Antares Speers-Waller.
