I can't do the layout anymore. RSI.
not as loud in the same way.
It's not the loud; it's the way they click. Increasing tension until they buckle and then all tension is released.
I used to have close to 100WPM on a Model M. I've never been able to get over 80. Could be age, but I think the predictability and certainty of the keypress played a large part. You know, without any doubt, when you've got a positive keypress on a buckling spring.
Have you ever tried the Matias Click? I've read they're the closest thing to buckling spring on the market.
I wish there was a way to test drive them. I could buy some and seat them in something, but I don't think I'd really be able to tell without a full keyboard and a typing test. That's always been the issue: accessability.
