I liked TTC Gold Pink’s chewy feel but wanted a slightly heavier so tried some mStone springs from KPRepublic, mainly for wide variety of spring types at same weight. TX long (16mm) is what I’m currently using in most of my boards so included it in this photo as reference point.
As replacement for TTC Gold Pink, two winners:
- mStone 2-stage 55g - chewy like TTC Gold Pink, slightly heavier top weight
- mStone 18mm 55g - chewy like TX 16mm 60g, slightly heavier top weight
Two are close but differs slightly in how it’s chewy. 18mm is slightly heavier at top than 2-stage but the later is more bouncy at the bottom, making it closer to TTC Gold Pink. Because of heavier top weight, 18mm will feel more speedy or shorter in key travel and bottom out more loudly, making it more appropriate for great sounding switches like Cherry black. TTC Gold Pink is loud and decently nice sounding but not at the Cherry black level (in my mind) so 2-stage makes more sense.
Both mStone 3-stage and 20mm felt tad too heavy at top for prolonged use but are promising enough to try them again at lower weight.
NOTE: Since these springs don’t come with spring top weight, I went with 55g bottom-out weight to get a good feel for how these irregular springs differ. Too early to generalize nor expect linear dynamics but, for at least 18mm and two-stage, reducing usual bottom-out by 5g is a good start. For 3-stage and 20mm, I’d reduce by 7~10g.
DISCLAIMER: I could be wrong and have been wrong countless times (lost count out of self-interest) so take a basketball sized grain of salt before bed and don’t call me in the morning.
