I just got some cherry profile switches and it's taken some getting used to, but I came from using DSA for many months and xda before that, so it might just be what I'm used to. Personally, I always prefer flatter profiles, but I think a nice sculpt looks more interesting. More annoying to switch out though.

Is that a sat 75? Respect!

Maybe GMK Dots in black. Though there are no letters, so you have to be good at typing, haha.

I've only been into keebs for a few years now so I have just a few sets of keycaps and boards, but so far, I'd say every 6 months or so (or once or twice a year) is my pattern of changing things up. I'll be building a new board toward the end of the year so that'll give me something else to build, and I already have my eye on two new keycap sets, so I think when I have more options, I might change out my main board every 3-4 months or once per season. That's mostly for keycaps, but usually if I'm changing out the keyboard, I'm also doing other changes to my whole desk setup, so I just like to make things match.

I don't know that I'd change switches that much though since I like to leave the switches as they are unless I find something better.
