I currently have a spyderco sharpmaker but am not able to to get the edges I want on some of my higher quality steels (primarily s30v). I am eyeing the lansky deluxe sharpening system and then buying the mount and leather stropping attachment as well. I was wondering if people normally get the diamond version or the stone version. It's a pretty big price difference so unless there is a good reason why I need the diamond I will stick with the stone stuff. Also, have people had good success with getting mirror edges or at least very sharp edges using the lansky stone system with the leather stropping attachment?
With S30V, you'll want at least one diamond hone (maybe Coarse/XC) to handle heavier edge repairs or rebevelling. The AlOx/corundum hones in Extra-Coarse, Coarse and Medium grit in the Deluxe set will struggle with such tasks, taking 2X-3X as long to accomplish the same work, IF it can get it done at all. I ruined two of them in my Deluxe set (they glazed and dished), in attempting to reprofile an S30V blade.
Frankly, if immediately jumping into sharpening S30V with a Lansky system, I wouldn't even bother with the Deluxe set, and instead go with a diamond set. That's what I did, after the lesson taught me by trying to rebevel that S30V blade; my Deluxe set got 'retired' after that. The Fine & UF ceramics in the Deluxe set (600 & 1000) are still quite useful for refinement and polishing of many blades, so you might consider purchasing those separately, to supplement a diamond set.
BTW, with a guided setup, I don't think I'd even bother with the leather 'stropping' hone; it's very small size will greatly limit it's usefulness, especially if mirrored edges are the goal. You'd do just as well (or likely better) by just temporarily attaching some paper with compound on one of the ceramic hones (600/1000) mentioned above. It'll be firmer (edges will be crisper), and you'll have much greater range of polishing capability, depending on which compounds you use with it (diamond compound is great with S30V, in particular). A bare leather strop is limited in usefulness anyway, as it doesn't really polish at all by itself, and the edge already needs to be very refined to benefit from it; a tiny 4" x 1/2" bare leather strop will be even more limited in usefulness.
