Sadly printing out 2D layouts doesn't work for contoured keyboards. Switching to the contoured Kinesis Advantage was the largest improvement for me (much better than the Kyria, Ferris Sweep, Moonlander, or Keyboardio Model 100). I would've never tried the Advantage if I had used a flat keyboard comparison tool.
(Now using a Glove80, which provides benefits over the Advantage2 and doesn't have the issues of the Advantage360 Pro.)
