I prefer to use my 80key ErgoDox.
But very often just stick with the QFR at hand.

Or 7bit Phantom.
What a very creative alternative layout for your QFR. I particularly like the index placement of brackets at Y's original place.
Where is your tilde and backtick key ("~ `") ?
I wish I have an ErgoDox but I'm afraid there's no switching back from this nonconforming setup. The newly released white ErgoDox set looks gorgeous by the way.
On your ErgoDox, there are so many Ctrl keys, which one (or a few) do you use most?
And have your developed any "thumb pain" using ErgoDox? (http://xahlee.info/kbd/ergodox_keyboard_thumb_keys_pain.html)
