I haven't used it personally, so I can't tell you any particulars. But just be aware there is an older and newer model with this name. I don't know what year the change came. The new model is officially called the "SLC neu" but a lot of times people leave that out, and you're left wondering which it is.
The way to tell the difference is, the older model is a dull drab green, and the armored coating extends right up to the hinge. The newer model is a darker forest green, and the area near the hinge is bare of armor, showing exposed black metal.
The reason I'd look for the newer model is, it has better coatings, especially the "Swarobright" or dielectric prism coating, for noticeably higher light transmission. Also it will have the "Swarotop" or water shedding and easy cleaning coating. What I really like about that is not so much its advertised advantage, as the fact that it is more resistant to eyelens fogging in cold or damp conditions.
Otherwise I don't think the glass design or mechanics are appreciably different.
I'll let other people tell you how good it is, what else you should consider, etc. But from what little I know, I'd be proud to have one myself!
