Even though I hate clamshell housing and dustproof stems, I had to give these a 5 star rating because they are an amazingly good switch for this price. The tactility is mild - half-way between a Cherry Brown and Ergo Clear in terms of prominence and sharpness of the bump. The spring weight is comfortable. They are smooth stock and have a clean deep but muted sound profile. But, there is a bit of leaf ticking and it's quite prevalent in my batch but it's mostly disguised by the bottom out sound. A bit of lube on the stem (I recommend 3203 to keep original sound profile) and oil on the springs and these bad boys sing! A bit of grease behind the leaf arch will eliminate almost all of the ticking if you want to go that far. No need for film at all - only very thin film can be applied and it makes almost no difference to sound and it's not needed for performance. I wouldn't recommend lighter springs as this more or less removes any tactility. Heavier springs (I tried 63.5g long) offer a slightly more rounded and prominent feel, but I reckon if you go too heavy (>65g) then this will also flatten out the bump. In the end, I feel like the switch is really well designed as is, responds well to a few mods, provides a comfortable typing experience, and offers a muted sound profile that isn't dull - all for a really good price. Highly recommended.
