Welcome to Geekhack!
TECK does seem an unusual layout, or at least different to what I am accustomed to.
Is there a particular reason you chose this keyboard? One solution might be to get a more conventional layout keyboard with MX blues.
I really liked the split design with vertical staggered keys, rather than the usual horizontal staggering. I was also looking for something without numpad and
ergonomic, so this was the choice I made. It takes some time to get used to the slash/question mark/quote keys, but I found out it only took like a week to get used to it.
I've never had a problem with tired fingers or pain as a result of continuous hours on the keyboard after buying this, so I guess it's been a nice investment, though I'm thinking on building myself an Ergodox
