I found the extra keys on the extreme left of the freestyle 2 to be really frustrating - I kept inadvertently hitting them and triggering all sorts of weirdness.
Apart from that I found the split-keyboard in general to be super-challenging for my brain for some reason and I generally found the whole thing to be torture. This wasn't helped by a sticky enter key (literally stuck down) - Kinesis were prepared to fix it, but I would have to pay to get it send back and forth from the US which was excessive on top of the already high price of the keyboard.
There were moments of the potential - brief fleeting moments of totally relaxed shoulders, my hands 50cm apart leaving my chest wide open and generally pretty laid back.
Ultimately though it was a bit a challenge I wasn't prepared to put up with and abandoned the split keyboard experiment after a few months.
I have similar experiences with high end keyboards like the Kinesis advantage and the HHKB2. As much as the internet likes to rave about these keyboards, they just are not for me.
