I want to order a set but after these last couple pages of things I don't understand I'm not so sure anymore.
I'd say you shouldn't let thickness be an issue for you. Sure, you can get thicker ones, but it'snot really necessary. I have WYSE thick doubleshots, and WYSE thin ones. While I sort of prefer the thick ones, there really isn't a difference typing on them. From a physcs perspective, you might end up with different resonances when you bottom out the key, but this shouldn't be as issue for anyone.
Me, I want a White/green sphercial PBT set in Dvorak, and when the closest I can get to that happens, (likely all but spherical) I'll wait until there are some options (or at least reviews) and then go for it.
