I have a couple pair on the list; a SLC HD (8x42) and SLC Neu 10x42. I use the 8x42 for hunting, the wide field of view (408') are best in in class. Most of my hunting is in heavy cover and archery so I'm closer by the nature of the hunt, but I'm still able to see good detail the few places where I can scan distances. The weight is reasonable (lighter the the SLC 28 vs 31 oz) and they balance great, I really like the ergonomics. I'm very pleased with the image and natural color from the binoculars. I really like the usable field of view, I do see some distortion at the very edge of the optic, I don't know if this is the pincushion or what the correct term is. You can see if only if you look really hard for it and quite honestly it's uncomfortable to try to look at this, so I don't consider it a flaw. I really like the twist up eye cups over the SLC, as they have more eye relief and better click adjustments. I also prefer the the diopter adjustment on this pair vs. the SLC. The focus is a little stiff, but maybe this is because of limited use, the SLC focus adjustment is smoother. These seem to have a better depth of view that doesn't require constant adjustment, but maybe this is better at 8x vs 10x?
The SLC Neu are excellent too. I use these for use at the archery range. The extra magnification helps pick up arrows and lines out past 40 yards better than the 8x. I'm not crazy about the diopter adjustment, because it seems easier to bump out of place. The eye relief works well for me, but I prefer the HD. The image quality between both of these is very similar and I'm not sure if I can tell them apart. Both have the slight distortion at the very perimeter of the view, but I'm not sure who really uses this, it give me a headache to even try to look through them at the far edge. To me the large useable FOV is what is important.
That being said, I've considered selling them to try the new Razor HD. I like the wider FOV and lighter weight, but I haven't seen these in person so I'm hesitant. I also really like the reviews of the Meopta Meostar HD. The weight and FOV are similar to the SLC, so again it would just depend on what I gain in the HD glass edge. I think the Swarovski may retain their value better than the Razor and Meopta too. My SLC's are a 2010 model and I've seen 2003 models still sell for $900+.
