From what I've read, very few people who buy ortho split keyboards, even people who love and swear by them, ever recover their WPM. I could never get comfortable on my Ergodox. The Glove80 seems more promising, but I can't afford the productivity hit at work, particularly when communicating on Slack. But the Kinesis Freestyle2 with the tenting kit quickly became my daily driver & basically solved my wrist and thumb pain.
