before i write about sp-star grey, here is a brief note on jwick switches.

jwick is the 'actual' brand name for switches made by jwk, which is behind waves after waves of oem custom/recolored switches for the past years. contrary to those custom switches, jwick switches are affordable (at 0.60myr each), mass-produced by jwk. they are at the same price point as gateron's famous affordable lineup, such as ks-3. currently, this series of jwick is mainly sold by Everglide, consisting of 3 linear with different spring weights, i.e. 江小白 white (37g), 江小红 red (60g), and 江小黄 yellow (65g)

here are some observations:

1. housing. its switch top is pc, while the bottom housing is nylon, 5-pin/pcb-mount. normally, with this kind of pc/nylon combo at that price range, switch top wobbles are imminent. (compared to gateron's equivalents). however, at stock, jwick switches show minimal to no wobbles (probably because what i have now is from the initial batch, made by molds that are still new);

2. slider. they have relatively minimal stem wobbles. on the hand, gateron switches have significant stem wobbles;

3. springs. the stock springs have some levels of pings, and they make crunchy sound. lubing with oil like krytox gpl 105 will fix this;

4. smoothness. jwick switches is relatively smooth. usually, tighter tolerance (i.e. minimal stem wobbles) means more frictions. (like cherry mx; it's the main source of scratchiness in them) however, this is not obvious in jwick switches at stock.

imo, they are good alternatives to gateron switches in general, if you preferred the qualities above.

as usual, if you modified these switches, it's better to add switch films to secure the housings properly, to prevent switch top wobbles.
