I too was interested in the HEST and had a chance to examine two lightly used examples and f&f left me a little flat and one had some blade play. In addition, I've seen a number of reviews stating blade play to be an isuue on some 2.0's FWIW, and I ultimately passed on the HEST. I did recently get a new Techno and it has been better than I hoped in terms of f&f, and materials. Having been carrying the Sage 2 around for awhile (and Sage 1 before that) I was beyond happy with the quality and ergos of these Spyderco Taichung knives and they were basically why I bought the Techno. I also considered a Strider PT (since I was looking for a beefy small quality Ti framelock/RIL) but simply couldn't find one. The Techno is so good on so many levels though I've lost interest it trying to track down any other small overbuilt folder.
EDIT: * I forgot to add the most important feature of the Techno besides all the obvious atributes already cited in the numerous reviews available re: solid lock-up, deep carry wire clip, etc., and that is...it cuts and slices VERY WELL and the 4.5mm spine thickness is hardly a hinderance at all! It tapers so thin just behing the cutting edge that not only does it hold its own cutting and slicing, but has the ruggedness with that thick spine as well making it quite a remarkable small folder.
