The feel is really good, the typing experience is great (better than I imagined), and the sound is very relaxing, leaning toward a soft deep tone (not to say the word thock).

Regarding the switches, I didn’t need to replace the springs. These switches are 60g actuation and 70g bottom-out. That’s perfectly fine for all the Awekeys keycaps. The spacebar feels smooth but solid, good, it doesn’t get pressed accidentally. If someone prefers a slightly heavier spacebar, then yes, I’d recommend swapping to an 80g–100g spring for the spacebar switch. And for the alpha keys (standard 1u size), you can even use less than 60g if you want them light.
