One of our Kickstarter stretch goals was adding lighter springs to the store, so we made 20 gram springs available for purchase.
So this begs the question, should I swap my springs? Well it depends on your skills and aspirations.
If you are just a beginner, you should probably stick to the default 35 gram springs on the Uni. This is because you don't want to be accidentally pressing keys all the time when you're just starting out.
You should be developing good muscle memory without spending too much time hovering your hand above the keyboard. When you're just starting out, your hands spend a lot of the time trying to figure out what to press next. Ideally, you want to be able to comfortably rest your fingers on top of the keys without it accidentally registering as you figure out your next stroke.
On the other hand, when you're more advanced, you might want to think about getting lighter springs. When you're fast, you don't think about what to type next. This is because it's engraved into your instinct. Your hands are either pressing down a stroke or getting ready to stroke the next word. There is no in-between time spent figuring out how to do the next word.
This, of course, is not a rule set in stone. Maybe you're still a beginner, but you want to, or need to, use lighter springs. Or maybe you're very advanced, but you don't like having to hover your hand above the keyboard.
It depends on your preference, which just requires having to mess around with the different options and finding what you like. But the best part is, you can always switch back if you don't like light springs and vice versa.
But how does one swap springs? Well we made a video for that:
TIP: Instead of opening, swapping, closing each switch one by one— open all the switches at once then go back and put in the spring and close the switch one by one. This way, you don't have to pick up the tweezer 28 separate times because you get to open all the switches in one go.
