I only tested the trampoline mod on sample switches, yet on my limited trials, I experienced an o-ring/stem/pole jam, it's a micro-jam, it feels mostly like mushiness
On a full board that gets pressed a lot, it seems to me that this micro-jam might be an issue, have anyone used the trampoline-mod for prolonged times, more importantly, have anyone tested silicone balls for a long time?
These silicone balls seem like a much much better idea, but as I haven't ordered them yet, I have no idea how they compare or whether they are able to jam too or not, but unless one has the ability to glue these pieces into the pole, I guess silicone balls should be better than the o-rings
(How is the ordering experience from imsto.cn?)
(offtopic, It's also possible to stack multiple o-rings with D/SA keycaps, I've been using my keycaps with double o-rings, no issues up until now, but the trampoline mod is obviously superior, if it works consistently)
